Problems during login

[Armando_3]

HI
I am not able to login to my system with any user , even with root.
After type my user name, the server sends the next message: "aud switch: not owner" and sends again the login line.
the only way i can get into my sistem is in maintence mode, but when i start up the server to level 2 or 3 is the same problem.
Could somebady help me ?
thanks in advance.

Someone has been playing with the permission in the /usr/bin directory. /usr/bin/login has probably lost it's SUID bit or ownerships. It should have: -rwsr-xr-x and owned by root:bin. In single user mode, check /usr/bin/login (you'll need to mount /usr first). Change it to the correct values with:

chmod 4755 /usr/bin/login
chown root:bin /usr/bin/login

Now boot into multi-user mode and all should work OK (assuming other programs were not changed.

Hi,

Are you in trusted system may be the trusted database was corrupt,after boot into maintainance mode unconvert the trusted
#/usr/lbin/tsconvert -r

change root password
boot to multi user by init 3
try login , if you can then reboot
after successful login then convert to trusted again.
