LDAP not enabled for Exchange

I installed Exchange 5.5 with Service Pack 3. I change the port numbers on LDAP to 1024 per a previous email. But when the install goes out to check system I keep getting LDAP is not enabled for Exchange site. From what I can tell it does look like LDAP is enabled. I am running this on WIN2k. Any suggestions.<br><br>

Re: LDAP not enabled for Exchange

The only thing I can suggest is to make sure you set the LDAP port value and make sure it’s enabled on the server Unity is installed on in the Exchange administrator (not the site container) and to make sure you have disabled the “inherit from site” option on the server object. I’ve seen a number of people miss this (it’s easy… the UI is not real clear on this). If that’s done correctly and the Unity setup is still barking at you about the LDAP protocol, you’ll need to get in contact with our support folks since that’s the only reason that message should show up.

Re: LDAP not enabled for Exchange

Make sure LDAP is configured at the Configuration Level in Exchange and the "Enable Protocol" box is checked.

You can also check that the first four boxes are checked under the Authentication tab:
Basic (Clear Text)
Basic (Clear Text)using SSL
Windows NT Challange/Response
Windows NT Challange/Response using SSL

Check that the LDAP port on the server level is also set for 1024. You will want the "Use site defaults for all properties" box checked off (instead of "Enable Protocol") and the same four boxes checked for Authentication as above.

I have had to reboot before I could get the LDAP port changes to be accepted by the Unity install. I did not have the patience to wait for a synchronization (I am not certain that will eventually occur - maybe someone will comment on that).

When you are using Windows 2000 LDAP port 389 is used for the Active Directory (the default LDAP port for NT 4.0 is 389) so we are recommending LDAP port 2015 but 1024 should be available and work for you.

I hope that helps. Thanks.

Re: LDAP not enabled for Exchange

Another small tid-bit;

Even though Unity allows you to continue the installation when it cannot detect the LDAP server (Which I think personally, this shouldn't be the case). You need to re-install Unity once the ports are sorted out.

The reason for this, is that if it cannot create the Unity folders in the X.500 directory (Exchange) during installation, they will not be created at all and the DOH will fail to start.

Learned this one the hard way :-)

PS: Jim, why is there no Unity 'uninstall'? Had to blow everything away manually (including registry entries) to re-install Unity properly.

Cheers!
John.
