Hi

I have just configured a Sharp MX2600 MFD to pull address off out Active Directory which is in a Server 2008 DC.

The problem is that the connection test is failing, returning error 3333 which states "LDAP Port is invalid", even though I have specified port 389 (the default LDAP port) in the printer configuration.

Is there anything I need to do on the server to make sure it's listening on port 389? How can I check it?

I think a basic "Telnet YourLDAPServerIPAddress 389" would allow to check that the port is being listened to on the LDAP server.

You should get a "can not connect" which will prove your favorite "network admin" that he has a IP/port to open on his super-secured firewall...

Thanks...

I am that network admin :-) and port 389 is open. In fact just to make sure  I opened all the ports for a minute and tested it again.

Before setting the LDAP authentication on your printer, were you able to print ?
Did you try to telnet your DC on port 389 ?
Did you try refering to your DC server using an IP instead of its name ?

Are you sure that the printer security settings does not enforce SSL for LDAP (Port 636 or 3269) instead of LDAP (389) ?

I found the problem!

All the settings were correct, except one: Enable LDAP! I don't know how I managed to miss it but I did.

All your suggestions were valid so I'm awarding you points anyway!

Thanks!
