Same login to Server Admin, multiple servers

Hello,
A few months ago, I set up 2 servers running 10.4.10 Server, one set up as OD master and the other set as Connected to Directory System. I was able to use the same login information to access all services on both servers, for example Server Admin, Workgroup Manager, etc. However, I needed to change rebuild the OD master and change the hostname. I don’t recall how I set it up originally, but I can not use the same login for both servers any more. I have set it up as Connected to Directory System and OD replica, and I can’t login under any of those settings. When server 2 is an OD replica, logging into Workgroup Manager as the local admin does not show the directory on the OD master.

Any way to fix this? Thanks!
