Subject: Re: Knox LDAP group filer is not working
If you are using the demo LDAP server then memberOf isn't available. It is an
LDAP extension that only exists in AD. Apache DS LDAP doesn't support virtual
attributes. If you want to emulate it you would need to update the user object
with the attributes.

Assuming you are referring to something like KNOX-1307 [1]? The user search
filter you can create can filter by groups depending on what you are trying to
do. memberOf is one way for AD to limit users to only ones in a certain group.

Hi,
We are trying to filter users by specific. LDAP groups, tried several options
provided in the documentation :
https://knox.apache.org/books/knox-1-1-0/user-guide.html#Advanced+LDAP+Authentication
User Search by Filter
· userSearchBase (Required)
· userSearchFilter (Required)
· userSearchScope (Optional)
· principalRegex (Optional)
Group filter is supported ? Do we have any working alternative to filter.
Users by group ?
Thanks
Raja
