SU and SSH not working.. HELP!!!

[dave_kimberley]

Hi,

If I try to SSH to my server as root, everything is fine, however if I use any other account, I will be logged in, but then kicked out.

When I try to su - to a user from root, I recieve the below:

su: warning: cannot change directory to /home/tas: Permission denied
su: /bin/bash: Permission denied

The below is also shown within /var/log/secure

Sep 15 12:05:27 tas su: pam_succeed_if: requirement "uid < 100" not met by user "tas"

I am using FC2 with kernel 2.6.8-1.521

Please can some one help, this is driving me mad..

did you have problems before 2.6.8. this kernel is known to cause all sort of problems, but it shouldn't affect ssh.

I have just completed a fresh install, and everything was working fine. Upto about 1hr ago.

what user id are you using?

[dave_kimberley]

I am root trying to su to tas, a user I have created. However from reviewing log files, any su attempt is not working.

Maybe a file permission problem?

what does
ll /home
return?

if it is not tas as the owner;

ssh in as root, then try
chown -R tas:tas /home/tas

First error obviously looks like a file permission problem, but the second I think should not be there if it did in fact authenticate as he should still have access to /bin/bash. But it might be worth a look/try?

I have changed the permissions on /home/tas, but I still get the below error when I try to su to the user

su: /bin/ksh: Permission denied

I have tried to change the shell within /etc/passwd and still the same error, just with the other shell.

I have also added another user, it seems that this problem occurs with any??

Please, any one seen this before?

FIXED!!!!!!

For some strange reason, the /bin directory had 700 permissions?? Back to 755.

Thanks everyone..
