Ask a question

LDAP registry location - can we have two of them ?

Peter Turvey (99127) | asked Sep 27 '18, 4:47 a.m.

We are using version 6.0.2 of the CLM applications. And Tomcat is version 7.0.59.

At the moment the "Server / Advance Properties" has
LDAP Registry Location = ldap://DC1:3268

I would like to add a second LDAP Registry location in case our DC1 is ever unavailable.

Is this as simple as editing the location to be
LDAP Registry Location = ldap://DC1:3268, ldap:DC2:3268           

Thanks   Peter

I added the second Domain Controller using the Jazz Team Server's "Configuration / Advanced Properties" page.
So I now have :
 LDAP Registry Location = ldap://DC1:3268, ldap:DC2:3268

This new setting was saved successfully but it didn't seem to do anything useful.

i.e. when I shutdown DC1 I was hoping the rtc users would still be able to log on (using DC2 as the LDAP registry location).

But they couldn't.

 Not directly in RTC. Even if it were available, a better solution is an HA type LDAP, where users it a virtual IP rather than the actual IP. I would imagine you have other products that need LDAP access, and as such are just as vulnerable to an outage. In such a situation, you should refactor your LDAP architecture to account for high availability:

Take a look at this article:

Thanks for that, I will discuss with the other network Sys Admins.
