Hi Friends
I have a problem, my machine is a rp2405, SO UNIX 11i.
When I change the password of any user did not match at the login prompt. The system send a message "login incorrect".
With the su command the system send "set groups: not owner" message.

Thak you

Hi,

Is your password file intact ? See through some allready logged in user or try logging in as root from console.

Also note that you should not use special characters like @,# in the passwords.

From man passwd
=============================
WARNINGS
Avoid password characters which have special meaning to the tty driver, such as # (erase) and @ (kill). You may not be able to login with these characters.

HTH,
Devender

Hi Eduardo:

Make sure that the '/usr/bin/su' executable is owned by root with its set userid bit (suid) on. An 'ls' should return:

-r-sr-xr-x 1 root bin ...

If not, fix with:

# chmod 04555 /usr/bin/su

Make sure, too, that '/etc/passwd' is readable by everyone: -r--r--r--

Regards!

...JRF...

Thanks James, these are my files
-r--r--r-- 1 root sys 1521 Sep 5 16:52 /etc/passwd

and

-r-sr-xr-x 1 bin bin 28672 Oct 4 2002 /usr/bin/su

I owned to root /usr/bin/su and now the problem happens with the trusted system mode

Thanx Devender... Thanx James.
The problem was owner in /usr/bin/login, I changed it bin to root.
