Hello All, I'm happy to be a part of the members of this forum, I'm trying to implement PHP AD LDAP Authenticator. I have managed to set it up so I can authenticate parent domain users. example.local (parent domain) As I have other child domains: site1.example.local site2.example.local I cannot make it authenticate other child domains. I have tried connecting to port 3268 on LDAP to be able to search all forest but Kayako seems cannot athenticate them. Can anyone help me regarding this? Thanks!
