CRITICAL main - Unexpected LDAP failure reading group members: {'desc': 'Critical extension is unavailable'}

I am running the UST v2.2.2 against Oracle Directory Enterprise Directory 11g Release 1. However, I am getting following error

2018-01-04 21:25:43 25356 CRITICAL main - Unexpected LDAP failure reading group members: {'desc': 'Critical extension is unavailable'}

I tried to narrow down the issue that seems to be in paged LDAP query or directory_ldap.py: iter_search_result code for Oracle Directory, I have created a script test_dir2.py.txt which also report same issue.

The ldapsearch seems to return correct results. Same UST's setup work for AD (with correct AD filters).

It seems Oracle Directory Enterprise Edition 11g Release 1 does not support PagedResults which throws this error.

supportedControl.txt - List of Available Controls for Oracle Directory Server, Simple Page Mode Control ( 1.2.840.113556.1.4.319) does not exist in the list

However, the UST seems to return correct results from directory when I do connection.search(...) (without PagedResults) in directory_ldap.py: iter_search_result code
