sa-ldapsearch: unable to use partial wildcard in LDAP queries

Path Finder

Hello,

We upgraded SA-Ldapsearch from 2.1.4 to 2.2.0 and since the upgrade we are unable to do some LDAP queries using "partial" wildcards.

Working:

|ldapsearch limit=1 search="(sAMAccountName=Username)" 
|ldapsearch limit=1 search="(sAMAccountName=*)" 

Not working:

|ldapsearch limit=1 search="(sAMAccountName=User*)" 

(Note the * after part of the username)

It throws the following error:

External search command 'ldapsearch' returned error code 1. Script output = "error_message=AttributeError at "C:\Program Files\Splunk\etc\apps\SA-ldapsearch\bin\packages\ldap3\operation\search.py", line 482 : Initial instance has no attribute 'hasValue' " 

Extract from the logs:

It was working fine with the 2.1.x version of the App.

I opened a case with support (1287612) and will update on results.

Any news on this? We have the same problem and still no new version. I wont change anything in the code. Whats about a fixed app version, splunk?,

Confirmed workaround is to revert the old part of the problematic function in search.py:
