LDAP user filter and GUID


I would like to know if it’s possible to use somehow GUID in ‘user_filter’ ?
I havent found any examples, but i want to be sure.

If yes, would you share some examples?
I would be very grateful. Thanks!

The search filter is typically provided in a standardized format, which supports defining binary values (ObjectGUID carries a binary value) as escaped hexadecimals:


The double backslashes are to escape the backslash character, in GitLab’s Ruby configuration files.

Are you facing an error with such a definition?
