Re: Invalid LDAP server: Timed out |and | Invalid LDAP server: Can't contact LDAP server
I know its a bit old, but I have a better answer for this for new comers.
The problem is not related to time-out , because the ldap is 1 ms away from the fortigate.
its not related to source-ip because I build a simple scenario and I got the same error , even without the vpn-tunnel.
The solution was in Distinguished Name.
And by the way, there is a misunderstanding here about the DN, its where you want the fortigate to start searching for the users. make sure you define it correctly.
