Hi,

While i am able login as a root by su -

so i am checked the /tcb/files/auth/r/root ... but i am not able to find out any of clues.

Below is my o/p of the /tcb/files/auth/r/root file

alicgd> more /tcb/files/auth/r/root
root:u_name=root:u_id#0:\
:u_pwd=QjhOwFxpHe0mM:\

Shalom,

It is not talking about the root user, its talking about the id you are using to su - from.

Check that ID.

Also check pam configuration. Many systems block this feature for security and auditing reasons.

Have a look at this thread:

In a nutshell:

There may be corruption in the /tcb structures. Run 'authck -a' to see if any problems are reported. If so, fix them and then try your su again.

Shalom,

The pam configuration looks good. Nobody has deliberately tried to stop su - login, though its trivial to do so.

I'm leaning toward /tcb corruption now. If it is not too large, please post the results of the authck -a command or post highlights.

Re: not able to su -

Hi,

I have a concern like can i copy the /tcb/auth/files/ by the ignite backup. If we take the ignite backup all the configuration files need to be there in the ignite tape right ?.. so is there a way to copy that file from teh ignite tape, is yes.. please let me know how to do that.
