SessionFactory.makeObject() exit
WARNING: Your password has expired.
Password change required but no TTY available.
alResponse[null]
=========================================================================================
Notice the second to last line. "Password change required but no TTY
available."
We reset the password. Try again. It works the first time but the warning
reappears immediately afterwords.
We noticed that the shadow password file gets deleted on the server after
first login resulting in the warning on subsequent attempts.
We are using Jakarta Commons Pooling to create a pool of JSch sessions.
Logs for SessionFactory.makeObject() refers to the pool access.
Ideas anyone? We are also in the process of contacting SCO Unix support in
the meanwhile.
