Can someone kindly point me to a howto on how to configure OpenLDAP 2.4 so that I may use the directory from Outlook?
So far, the articles I've found (such as https://www.maxcrc.de/en/use-openldap-as-address-book-for-outlook-en/) mention the steps for previous versions, but the filenames in 2.4 have changed. Furthermore, I see that the officePerson.schema file does exist in /etc/openldap/schema directory. I assume that this means that I need to add this schema by first creating an LDIF file and then using ldapmodify?
I have openLDAP installed on a CentOS 7 server. All the entries I have created so far use the organizationalPerson structural class. Would I need to recreate them? If so, can I add the needed attributes to the organizationalPerson class so I wouldn't have to recreate everything? I am using LDAP to login to a large number of Linux machines via ssh, Java apps running under WebLogic, etc.

I've created a test cloud spanner instance and database have have been attempting to connect to it through DBVisualizer.
I have authenticated using the gcloud auth command, and have the driver set up within DBVisualizer.
The connection string I'm using is:
jdbc:cloudspanner://;Project=testapp;Instance=test-instance;Database=test-spanner;PvtKeyPath=/Users/userhome/.config/gcloud/application_default_credentials.json
However, when I try to connect I get the following error:
[Simba][SpannerJDBCDriver](100004) Failed to connect to Spanner: No NameResolverProviders found via ServiceLoader, including for DNS. This is probably due to a broken build. If using ProGuard, check your configuration
Is there anyway to get a connection from a DB Management Tool such as DB Visualizer?
I found a solution on MacOS at least. Copy the CloudSpannerJDBC42.jar and google-cloud-spanner-0.9.4-beta.jar to DBvisualizers lib folder. In the case of MacOS the location is:
/Applications/DbVisualizer.app/Contents/java/app/lib
Restart DBVisualizer and then you can connect.
I don't think DBVisualizer supports Cloud Spanner right now. See their documentation: https://www.dbvis.com/features/
As the product is still pretty new publicly, we'll hopefully be seeing more 3rd party support in the coming months.
I've run into similar problems with the driver supplied by Google, so I decided to develop my own. The driver has both a 'thin' version and a 'fat' version. The thin version is intended as a dependency to be included in Java applications you develop yourself. The thick version can be used for standalone purposes, such as these kind of connections. The thick version (and other) can be found here: https://github.com/olavloite/spanner-jdbc/releases
More information about the whole driver can be found on my GitHub page.
The driver does work with DBVisualizer. Follow these steps to set it up:
Download the driver and place it in your JRE/lib/ext directory (this is necessary because of dynamic loading of services done by the underlying Google Cloudspanner API). Make sure you place it in the lib/ext directory of the JRE you are actually using with DBVisualizer.
Open DBVisualizer and open Driver Manager. Click on Create a new Driver.
Give it the name Cloudspanner
URL format is jdbc:cloudspanner://localhost;Project=projectId;Instance=instanceId;Database=databaseName;PvtKeyPath=key_file
Driver class is automatically selected.
Close the Driver Manager and make a new connection using the new driver.
Where should the configuration.yml file of Dropwizard be saved?
I'm using Dropwizard which is a Java web framework.
Dropwizard uses configuration.yml files to load in environment specific configuration files.
In the example I found online the configuration.yml files contains username and password of databases.
Now the question is where to save this configuration files which contain password in plain text.
OPTION 1 GIT REPOSITORY
In the example the configuration.yml are part of the project. So one could keep them in the git repository with the rest of the code. This though is a well-known bad security practice.
If someone crack the git repository has access to the code and to the database. Also this way every single developer has access to all the passwords of all the environments.
OPTION 2 FILE ON THE COMPUTER
Safe the configuration.yml on the machine but do not store on the git repository
OPTION 3 ENVIRONMENT VARIABLES
Use configuration.yml file which point to environment variables on the specific machine.
This is not so practical since all this environment variables needs to be set manually on all the machines. Also what is the syntax to use ENVIRONMENT VARIABLES in Dropwizard's configuration.yml files?
I'd go with environment variables if you cannot control read access to the config file or are concerned that your machine is owned by an untrusted third party.
Environment variables are trivial to script.
You should use a file on the computer: this is how many frameworks out there work.
If you use a unix/linux server you can chmod 0600 [filename] and be sure that nobody (almost nobody as root can do anything) can read that file.
On the dropwizard ML it was also cited to use software like puppet/chef to deploy your application and using these frameworks to handle all variables (eg: different configurations for test/staging/production).

I'm working on an introspection utility which eventually asks the user to specify the executable to use for launching the application. Now I'd like to add support for so-called "Windows Store apps" (formerly known as "Metro" apps, I believe). However, it's not clear to me how they are stored locally.
I read about how Windows Store apps are packaged and deployed, and apparently it's common to distribute them as .appx files, generated by tools like makeappx. However, I don't see if/where they are stored locally.
Does it make sense to address them like ordinary executables at all, i.e. via a file name? Or is there rather a more appropriate method? I noticed that in the registry, some (all?) of the Windows Store apps I have installed are listed beneath
HKCU\Software\Classes\ActivatableClasses\Package
Is there some API available for handling this registry tree, to do stuff like "Get me the user-visible name" or "Get me the AppUserModelId so that I can launch the app"?
Has anyone here successfully connected to neo4j using ColdFusion?
I was able to connect to neo4j 1.6.1 using this guide as a starting point: http://ghostednotes.com/2010/04/29/using-neo4j-graph-databases-with-coldfusion
. However, it was a short lived success. I have since uninstalled neo4j 1.6.1 and installed 1.7.
I am now running Apache, CF 9.0.1 on windows XP as a local dev box. I added ...\neo4j-community-1.7\lib to my CF class path and the libraries are listed in CF Server Java Class Path. neo4j is running fine, as I can use their administrator interface: http://localhost:7474/webadmin/# . CF and Apache are also running fine. I use them daily.
While the code below works, I'd really like to 'see' what's going on using the neo4j web admininistrator. So I can coordinate my learning neo4j while using the data in a CF application.
Code: (Works)
dbroot = "/tmp/neo4jtest1/";
graphDb = createObject('java', 'org.neo4j.kernel.EmbeddedGraphDatabase');
graphDb.init( dbroot & 'var/myFirstGraphDB');
So I tried to connect to the neo4j db graph.db . However the code fails.
Code: (fails)
graphDb = createObject('java', 'org.neo4j.kernel.EmbeddedGraphDatabase');
graphDb.init( dbroot & 'graph.db');
Error:
Object instantiation exception.
An exception occurred while instantiating a Java object. The class must not be an interface or an abstract class. Error: ''.
If I remove the "." in graph.db it does create a "graphdb" in the neo4j data folder, and successfully connects to it. However, that db is not viewable with their admin :(
I'm a novice, so please dumb down your answer.
Ok, I think what you're trying to achieve is not possible. It is not possible to access Neo4J within CF (via Java) and have the admin interface working (caveat 1 applies).
If you have put all the jars of the Neo4J package into Adobe CF then most likely the Neo4J admin interface is looking at it's own Neo4J file system. When you create the Embedded server it is not connecting to the same database because it simply can't.
Embedded Neo4J doesn't work like a standard database connection. One Embedded Neo4J reads and writes to one directory location (key word: directory, it doesn't open a single file but a whole bunch of them). No two Neo4J instances can access the same directory location (caveat 2 applies).
Ok, the caveats:
1- it is possible, in theory, to manually start up the admin interface programatically so that it uses the Embedded server that you create via Java. The Java code looks simple enough (taken from Using the server (including web administration) with an embedded database):
// Create your embedded graph db somewhere
src = CreateObject("java", "org.neo4j.server.WrappingNeoServerBootstrapper")
.init(graphDb);
srv.start();
// The server is now running
// until we stop it:
srv.stop();
I did not get this working, mostly because the admin server hasa bunch of dependencies that were incompatible with the rest of my setup, so I can't advise on how well the above will work.
2- it is possible to have 1 read/write Neo4J accessing one location and then have multiple read-only Neo4Js (EmbeddedReadOnlyGraphDatabase) reading the same location (but I've never tried it).
You do have the option of using the REST interface - either manually, or via the Neo4J Java REST Binding (kinda slow, though).
It might be worth reading the Deployment Scenarios documentation before getting too deep in this.
There is at least one CF/Neo4J bridge out there, but it's pretty incomplete. I have one that I worked on, but I need to figure out if I can open source it!
Just a small addition to otupman's comments. I can confirm his theory of connecting to the admin interface from CF. Adding the following jars to the CF class path seemed to be enough to get the basics up and running. You may need additional jars if you are using more advanced features. Note, I am using Tomcat so the exact jars may differ slightly for your environment
neo4j-community-1.7/lib/*.* (entire directory)

Then started the server and database in onApplicationStart
factory = createObject("java", "org.neo4j.graphdb.factory.GraphDatabaseFactory");
dbroot = ExpandPath("/neo4jtest/");
graphDb = factory.newEmbeddedDatabase(dbroot & 'myFirstGraphDB');
Bootstrapper = createObject("java", "org.neo4j.server.WrappingNeoServerBootstrapper");
graphServer = Bootstrapper.init( graphDb );
graphServer.start();
application.graphServer = graphServer;
application.graphDb = graphDB;
And closed both in onApplicationEnd
application.graphDb.shutDown();
application.graphServer.stop();
Edit: After some further testing, I think is better to load them once in OnServerStart. Then use a shutdown hook to close them. But since this is just for a local development box, it is less critical.
I am trying to get the PowerBuilder 10.5.2 sample web services application running. I can open the workspace just fine, and I can see the objects and even run the app but I get a "bad runtime function reference" error when I try to invoke the service.
I believe I have installed all the requisite parts:
PB 10.5.2
.Net 2.0 SDK
Web searches reveal that some of the web services used by the sample app are defunct, but I can't imagine all of them are, so the error seems to indicate a problem with the setup or objects, not the third party services.
I can see pbwsclient105.pbd in the workspace list and in the Sybase shared objects directory. However, as a test, I tried to use the alternative method the documentation listed for setting up the PB proxy to the .Net web service objects (by importing PB extensions from pbwsclient105.pbx) and got a "invalid dll error" so perhaps my web service libraries are corrupted?
What else could be missing? Path settings? Incorrect .Net 2.0 SDK installation?
* * * Edit: Problem Solved - at least on my machine(s) * * *
I took a cue from the thread I found here and began examining what was happening with PowerBuilder when these errors occurred -- both during the import of the PBX and during runtime if you executed the sample application.
One person in the thread mentioned the issue was related to libeay32.dll and ssleay32.dll. This is not the first time OpenSSL has given me fits with these components -- my hard drive is littered with them in various application folders. These DLLs get loaded by PB when the PBWSCLIENT105.PBX extension is imported or by an app using the associated PBD at runtime. Sure enough, by using ProcMon, I was able to confirm that libeay32.dll and ssleay32.dll were being loaded from Windows\System32 as opposed to the version of the same DLLs located in the PB folder structure. Apparently, this is a problem. I renamed the two DLLs located in System32 to effectively remove them, fired up PB and the import of PBWSCLIENT105.PBX worked like a charm.
I have a similar issue with our PB 10.5 installation. Importing the PBX file gives me the error message:
---------- Import PB Extension:
Importing C:\Program Files\Sybase\Shared\PowerBuilder\pbwsclient105.pbx - Error: The file is not a valid dll or pbx file.
---------- Finished
I initially thought the issue was that the files were corrupt, etc. However, I installed PB 10.5 on a clean machine (a VM actually) along with the .Net 2.0 SDK and the import worked flawlessly; also, I was able to call a web service. Every developer in my group has the same problem on their own machines, but if they use a "clean" machine or VM with PB installed (and perhaps a few other apps), the import of the PBX file works without issue.
At this point I am trying to pin down what in the environment causes the problem, but haven't been able to yet. What's interesting, as you've noted, is that if you open the sample application, you can see the exact same imported libraries present; however, you get the error at runtime. All of this really points to something environmentally missing or incorrectly registered. So, if you have the ability to use a VM, I recommend that as a temporary work around.
One thing I'll add here: if you happen to use Vista or Windows 7 as your VM, the import of the library works fine, but I had issues generating the client-side proxy using the .Net web service engine. I finally discovered that in the background, the SDK tool WSDL.exe is being executed against the WSDL for the service in order to produce a .Net client-side proxy. Turns out that Vista/Win7 User Access Control was preventing WSDL.EXE from running. I ran PowerBuilder "as Administrator" and everything worked as expected in terms of generating the client-side proxy.
If you discover anything about why the PBX import doesn't work, I'd be interested in hearing about it!
