can not su

[Alan Casey]

Hi, I made some permission changes yesterday as part of an audit on out hp-ux 11.0 server.

As a result we now can not su to any user:
getting the following error su'ing to any id

"image1(ts9ac1)/home/ts9ac1> su -
Password:
su: Unknown id: root"

Any ideas where the permissions problem may be?
Thanks

What are the perms on /etc/passwd file?? Should be read to all.

[Alan Casey]

darwin-/ora_export/logs> ll /etc/passwd
-r--r--r-- 1 root swadm 939 Nov 21 11:52 /etc/passwd

[RAC_1]

type su
pwck
grpck

Also perms on /etc/profile, /etc/group

and the permissions of the /etc directory ?

# ls -lad /etc
dr-xr-xr-x 27 bin bin 6144 Nov 22 06:40 .

Hi,

As a part of these changes have you converted the system to Trusted System ?! I experienced the same behaviour when I converted one system to trusted system. If You made these changes through SAM, it will tell you that the system needs to be converted and ask you to reply with Yes or No.
