I had to add users to security group to fix the issue

 

Considering that tcb is not enabled on server,  is there any attribute that
might prevent

Users from reading security files ?

Subject: RE: problem with passwd file 

 

I just figured that everything is fine with root user,

I mean root user sees file's owner ship with username but for normal users 

File's owner ship is UID or numbers.

 

It should be permission problem.

 

Any idea that might help to find the cause and fix it.

Subject: problem with passwd file 

 

Hi

 

I just upgraded one of our AIX servers and after upgrade file's owner ship
shows up as number

For all users unless root user.

 

Users are exist in /etc/passwd file but commands can't find the user,

For example chown commands can't find user bin in password file 

But this user is exist in /etc/passwd file.

 

 

## ls -la smit.log

-rw-r--r--    1 112      1            148547 Dec 10 14:37 smit.log

 

## chown bin smit.log

chown: 3002-131 bin is an unknown username.

 

## grep "^bin" /etc/passwd

bin:!:2:2::/bin:

 

 

so far I tried following commands and still couldn't fix the issue.

 

usrck -y ALL

pwdck -y ALL

mkpasswd -c

 

any help would be appreciated.

Thanks
