Re: su root: 'incorrect password' / RH 9




Bob,
Thanks a lot for your prompt and kind advice.

When I did further exeperimenting by 'su ...', I found that the problem is not related
to 'root' user:  su does not accept _any_ user's pwd. (I can 'su' from within 'root'  shell
without supplying any pwd, that guided me to assume a root-only-related fault in first place)

In short: I can log in as any_user by using initial gui login,  but no user's pwd is valid when supplied on
command line, e.g  to 'su'  command (pls. don't assume caps_lock confusion et al)

I missed to mention, that I've installed binary samba 3 (RH rpm) from Linux.org in my box.
(not  available  on RH network yet.)
So far, I can work with my RH9 by using graphically supplied 'root' credentials, anyway.



Kind regards,
Martti Pitkanen

Hi,


After installing all sp:s for RH9, I came across a root authorization
problem:
As a regular user, I open 'Konsole - Super User Mode'. RH9 does not
accept root password. Anyway, I can boot as a 'root' without problem.
(runlevel 5)
After having booted as 'root', I 'su regular-user', in xterm window.
Then I 'su root' in the same windoe, which produces the above error,
i.e. I cannot return to 'root', even though I've booted as 'root'
originally.
Pls. see below the applicaple 'messages' -snippet:

Nov  6 15:28:12 Fuji2 su(pam_unix)[11527]: session opened for user root by
root(uid=0)
Nov  6 15:28:17 Fuji2 su(pam_unix)[11554]: session opened for user
regular-user by root(uid=0)
Nov  6 15:28:23 Fuji2 su(pam_unix)[11581]: authentication failure;
logname=root uid=500 euid=500 tty= ruser=regular-user rhost=  user=root

Authentication:
Use Shadow Passwords = yes
Use MD5 Passwords = Yes
all other selections = no
