How to get ansible.module_utils to resolve my custom directory - python-2.7

Question

Certain variables in ansible.cfg seem to not be taking affect.
Ansible 2.2.1.0
Python 2.7.10
Mac OS Version 10.12.5
We have created a custom class that will be used in our custom Ansible module. The class lives here:
/sites/utils/local/ansible/agt_module_utils/ldapData.py
/sites/utils/local/ansible/agt_module_utils/init.py
The class inside ldapData.py is named:
class ldapDataClass(object):
In all cases, init.py is a zero byte file.
Our Ansible module is located here:
/sites/utils/local/ansible/agt_modules/init.py
/sites/utils/local/ansible/agt_modules/agtWeblogic.py
The import statement in atgWeblogic looks as follows:
from ansible.module_utils.ldapData import ldapDataClass
I have also tried:
from ldapData import ldapDataClass
The config file has the following lines:
library = /sites/utils/local/ansible/att_modules
module_utils = /sites/utils/local/ansible/att_module_utils
When running our module, the modules directory IS resolved but the module_utils directory is not resolved. When the include is "from ansible.module_utils.ldapData import ldapDataClass" the failure is before ansible even connects to the remote machine. When the include is "from ldapData import ldapDataClass" the failure is on the remote machine. Below I am showing the failure "on the remote machine" (scroll right to see full error):
nverkland#local>ansible ecomtest37 -m agtWeblogic -a "action=stop instances=tst37-shop-main" -vvv
ecomtest37 | FAILED! => {
"changed": false,
"failed": true,
"invocation": {
"module_name": "agtWeblogic"
},
"module_stderr": "",
"module_stdout": "Traceback (most recent call last):\r\n File \"/tmp/ansible_FwHCmh/ansible_module_attWeblogic.py\", line 63, in <module>\r\n from ldapData import ldapDataClass\r\nImportError: No module named ldapData\r\n",
"msg": "MODULE FAILURE"
}
If I move the ldapData.py file into the "ansible installed" module_utils directory (/Library/Python/2.7/site-packages/ansible/module_utils/ on my Mac) the module runs fine. What have I done incorrectly in my config file that has prevented the use of my "custom" module_utils directory?
Thanks.

module_utils path is configurable since Ansible 2.3: changelog, PR.
I guess you have to upgrade or refactor the module.
Update: working example
Project tree:
.
├── ansible
│   └── ansible.cfg
├── module_utils
│   └── mycommon.py
└── modules
└── test_module.py
ansible.cfg:
[defaults]
library = ../modules
module_utils = ../module_utils
mycommon.py:
class MyCommonClass(object):
#staticmethod
def hello():
return 'world'
test_module.py:
#!/usr/bin/python
from ansible.module_utils.basic import *
from ansible.module_utils.mycommon import MyCommonClass
module = AnsibleModule(
argument_spec = dict()
)
module.exit_json(changed=True, hello=MyCommonClass.hello())
Execution:
$ ansible localhost -m test_module
[WARNING]: Host file not found: /etc/ansible/hosts
[WARNING]: provided hosts list is empty, only localhost is available
localhost | SUCCESS => {
"changed": true,
"hello": "world"
}
Ansible version:
$ ansible --version
ansible 2.3.1.0
config file = /<masked>/ansible/ansible.cfg
configured module search path = [u'../modules']
python version = 2.7.10 (default, Feb 7 2017, 00:08:15) [GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)]

Konstantin's notes helped. I managed to solve the riddle.
In my config file I had:
module_utils = /sites/utils/local/ansible/agt_module_utils
This causes Ansible to think that my class is found at:
import ansible.agt_module_utils.ldapData (working)
until now I was attempting to find the class at:
import ansible.module_utils.ldapData (broken)
