 |
|
Hi,
I'm running 4 Slamd64 boxes (11.0 and 12.0), and on 1 box only su is not
working anymore for common users... Each time I tried I got "Sorry", no
other explanation. Nothing seen in any log file :
marc@equinoxe:~$ su -
Password:
Sorry.
marc@equinoxe:~$
/var/adm/secure says :
Nov 11 11:13:27 equinoxe su[5334]: Authentication failed for root
Nov 11 11:13:27 equinoxe su[5334]: - pts/3 marc-root
Same reply with another user :
marc@equinoxe:~$ su - xxxx
Password:
Sorry.
Remote login using ssh is OK on this box, only local su seems to be broken.
I spent some time on google without success, diff file from other config
where su is working (my 3 installations are almost identical for the
system part, no sudo used or configured, no pam installed)
Any idea ?
Regards,
Marc.

setuid bit removed from file permissions? File system mounted such that
setuid bit is not honored (mounted with "nosuid" option)?

Thank you, this is the problem, corrected now. I guess the problem

tar didn't kept setuid bit on file ? --> so I while get some other problems.

Marc.
