Connect ldap to Global catalog

Hi Everyone.

For our kanboard i’m looking into using ldap for user authentication. Within our network we have two seperate domains with a two-way-trust.
After testing with ldap we are able to connect to one ldap domainl, according to the kanboard creator this is by design to keep the application simple and not bloated.

Today I read the release notes of version 1.2.19 and found that it should be possible to use the global catalog to get the userinformation. releasenotes : Kanboard v1.2.19

I have been busy trying to get this connection setup but without any luck. Does anyone know where I can find more information on connecting to the GC for kanboard?

Thanks very much in advance!
