Standard telnet protocol in telnetd uses a file called netlogin, written 
to adhere to standard Unix configuration. Logging in, or rather attempting
a log in into a non-standard and/or augmented system with modified /etc/passwd
file confuses the hell out of the protocol. 

One has to patch telnetd to make it read the actual password from /etc/shadow
(and /etc/security on RT AIX) so that a graceful login is permitted. Reading
an alphabet 'x' on Release 3.2 and the character '!' on selected AIX systems
thoroughly screws up the Telnet protocol. 

Alternatively, a kludge consisting of copying over the password field from
/etc/shadow and/or /etc/security to the standard place in /etc/passwd will
take you around the problem. 

Try the second method at first. The former one requiring a patch may be 
non-trivial.
