How can I get around Name too long for LOGINREC in pymssql without changing the username - python-2.7

Question

I am attempting to use pymssql to connect to a client's database, but have thus far been unable to succeed. I believe that the root of the problem is this entry in the stack trace of my TDSDUMP:
dblib.c:761:dbsetlname(0x1ac3e10, <username>#<servername>.database.windows.net, 2)
dblib.c:7929:dbperror((nil), 20042, 0)
dblib.c:7981:20042: "Name too long for LOGINREC field"
One problem is that <servername>.database.windows.net already exceeds the string limit (which seems to be 30 according to this: How to use PHP's dblib PDO driver with long usernames? / SQLSTATE[HY000] Name too long for LOGINREC field (severity 2)).
I have also attempted to exclude the #<servername>.database.windows.net portion in the username entry only to receive the following error:
msgno 40532: "Cannot open server "1433D" requested by the login. The login failed."
According to https://github.com/pymssql/pymssql/issues/330 the #<servername> portion is requested by the server.
So at this point, I attempted to do the following:
user = username + "#{}".format(server)
user = user[:30]
And I received the following information (which was a slight improvement but still not ideal, given that I could still not establish the connection):
"Cannot open server "<server_name minus the last 6 characters>" requested by the login. The login failed."
If possible, I would prefer passing some parameter to pymssql's connect method that would override this character limit or do something to append the server to the username on the backend after calling dbsetlname on just <username> without the #<servername> portion. Does anyone have any recommendations (again the preference is to not ask the client to change our username, but we may have to resort to that or trying to use pyodbc if there's no other option).
These are a few of the connection methods I have tried:
conn = pymssql.connect(
host=host,
database=database,
user=username,
password=password,
port=int(port) # this is 1433
)
conn = pymssql.connect(
host=host,
database=database,
user=username + '#{}'.format(servername),
password=password,
port=int(port) # this is 1433
)
conn = pymssql.connect(
server=<servername>.database.windows.net,
database=database,
user=username,
password=password,
port=int(port) # this is 1433
)
Thanks in advance for any help/advice that you may be able to offer!

Answer 1

You can probably use an alternate connecting string method.
If you're using SQL Server Auth, try this:
conn = pymssql.connect(
server="<servername>.database.windows.net",
port=1433,
user="username",
password="password",
database="dbname"
)
If you're using Windows Auth:
conn = pymssql.connect(
server="<servername>.database.windows.net",
port=1433,
user="DOMAIN\USERNAME",
password="password",
database="dbname"
)
Have you tried either of these connect methods?
