RHEL5 LDAP Migration to RHEL7

Posted on

Hi all!

So here's my current situation that has consumed about four weeks of my time attempting to figure out. We currently have a RHEL5 LDAP server that all our users authenticate to. I've installed and setup a RHEL7 IdM server. It works great and it was actually really easy to migrate with. The issue is that it uses kerberos authentication and overwrites the krb5.conf file. Our users are utilizing HPC's by using kerberos and can't if we use it to authenticate to both because of the configuration (correct me if I'm wrong, please).

Has aybody else ran into this problem of multiple programs attempting to use kerberos for authentication? If so, was there an actual solution to get both of them to work properly?
