Is your feature request related to a problem? Please describe.
we have problem using "memberof" filter

Describe the solution you'd like
be able to filter out based on a security group membership in AD.

Describe alternatives you've considered
have a config section that handles security group filtering

Additional context
when I add ldap_filter parameter like this: (&(objectclass=user)(memberof=CN=GroupName,OU=SomeOUName,DC=Domain,DC=COM)), the filtering returns error always.
