[Serusers] ALIAS not working, PLEASE HELP ME!

I believe I ran into a problem like this some time ago with version 
0.8.12 running on RedHat Linux 9. I was able to resolve this issue by 
reducing the FOREVER_REL value in serctl. 31536000

My old system is set to FOREVER_REL=31536000 which resolved the alias issue.

Hope this helps. Also, if you search the mailing list you can find the 
answer and the explanation of the problem.
