[cobalt-users] su not working

[Jan Ploski <jpljpl@xxxxxx>]

Hello,

Sorry if this question has already been asked (and answered) in the past,
but I did not find any archive for this list (is there one?)

I need to switch to root from an ordinary user, which I created with
useradd. Su just responds with "Invalid password". Interestingly,
I can su to root if I log in as admin, and I can su to admin from
my user account. However, if I do su to admin without logging in
as such, I cannot su to root (same "Invalid password" message).

The following messages are being logged in /var/log/auth
(if I try to su from my normal user account, the user name appears
instead of admin):

Apr 11 22:30:06 liquid PAM_pwdb[24819]: (su) session opened for user root by admin(uid=110)
Apr 11 22:30:44 liquid PAM_pwdb[21255]: (su) session closed for user root


Any ideas what the problem might be?

Thanks in advance -
JPL
