[Scottish] Help with SU

[Phillip Bennett]

Hi Kyle,

Yes, I removed winbind from the nsswitch.conf.  That was one of the first
places I checked.  I have found a post on another error I recieved and have
found that something has reset the permissions on the su executable.  I
actually thought I'd have tried to su to another valid user, but evidently I
hadn't.  I thought I'd try it again today and I got another error (su:
cannot set groups: Operation not permitted)

Apparently when the permissinos are set as : rwxr-xr-x  root   named  60480
Apr 10  2006 /bin/su it's not a good thing.

Goodness knows what the hell has happened, but I set the permissions back
to: -rwsr-xr-x  1 root root 60480 Apr 10  2006 /bin/su

And it's working again.

Thanks for all the help though.  It has been a very weird problem.  With
random permissions like this though, I think it might be time to rebuild.
Has anyone seen this type of thing before?

Phil.

Have you removed winbindd from nsswitch.conf?
