Hi.

I have courier-0.32 installed and running in two machines with RedHat 6.2, using authuserdb as the authentication method.

In one of these machines, I've updataded to 0.34 and everything is working ok. In the other one, the updating process was done exactly in the same way that the first one but when I try to do a pop authentication I get this error message:

"May 26 13:00:07 <myserver> pop3d: exec: No such file or directory"

and when I try to send a message to a box in this server, I get this other error message:

"May 26 12:04:51 <myserver> courieresmtpd: error,relay=::ffff:xxx.xxx.xxx.xxx,from=<user@myserver>,to=<anotheruser@myserver>: 550 User unknown."

I realized that in the first server (in which everything is working properly), there are four files in libexec/authlib: authcram, authcustom, authpam, authuserdb. But, in the second one, only authdaemond, authdaemonldap, etc, appears.

The compilation and installation process was done exactly in the same way in both machines. The system are the same (RedHat 6.2 - kernel 2.2.16-3), so why the authentication daemons weren't the same? Is it possible that the error messsage in the pop authentication is due this difference?

Thanks in advance and best regards.
