Check to see under /etc/passwd for the user you are trying to login with if their shell is pointing to /bin/login. If so, change it to the basic shell (/bin/sh) and see if that corrects the problem.

Hi,
check whether bos.rte.security is installed.
This package contains /usr/sbin/tsm.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

There is also an apar concerning problems in bos.rte.security related to /usr/sbin/tsm:
IZ19034
bos.rte.security 5.3.8.1
Please check it here:

Since /usr/sbin/tsm is part of bos.rte.security and tsm is not found, you'll have to reinstall the package  or recover tsm from backup.
Use 'overwrite same or newer versions: yes' when reinstalling via smit.
I hope reinstall will work, because bos.rte.security is tightly coupled with bos.rte.
Try 'preview only: yes' first!

Hi rammaghenthar,
if you can' t recover /usr/sbin/tsm, perhaps from another machine with bos.rte.security installed or from a backup, you should reinstall bos.rte.security.5.3.8 (if you really have TL 8 running) with the above precautions. It's a bit strange that your lslpp says you had bos.rte.security.5.3.0.53,
because TL8 contains bos.rte.security.5.3.8.
What does 'oslevel -s' say?
What 'instfix -i | grep ML' ? If you can't find 5300-08_AIX_ML here,  enter
'oslevel -rl 5300-08'
It's possible that you will have to re-run your update for TL8, but let's first look at the output of the above commands. Please post it, including the output of 'oslevel -qr'.

Also, the location for telnetd is /usr/sbin/telnetd. If telnetd is moved to another location, modify the inetd.conf accordingly. Check /etc/inetd.conf.

The minimal inetd.conf contents to make telnetd work:
telnet  stream  tcp6    nowait  root    /usr/sbin/telnetd      telnetd -a
