'could not open session'

I've just done an upgrade from RHEL3 to 4, and have run into the strangest
thing.

I can't log in from the console. Every login attempt with the correct password
gives the message 'could not open session'.

I can ssh in, and enter a username and password. But from there, I can't su to
anybody - root, or another user. 'could not open session'.

Booting to single user mode gives me root, but as soon as I do a su - you
guessed it.

I can do a sudo.

I enabled telnet, just to see what happens:

login: tim
Password:

Permission denied
Connection closed by foreign host.

Permission problem, I think - but _where_??
