PAM Error -- Need Help

I'm getting the following error when i checked /var/log/secure in my servers.

sudo: PAM unable to dlopen(/lib64/security/
sudo: PAM [error: /lib64/security/ cannot open shared object file: No such file or directory]
sudo: PAM adding faulty module: /lib64/security/
su: PAM unable to dlopen(/lib64/security/
su: PAM [error: /lib64/security/ cannot open shared object file: No such file or directory]
su: PAM adding faulty module: /lib64/security/

I've observed the same error in most of the servers i got.

Is this common error or anything i'll have to do. googled a lot and didn't get any anser anywhere.

i'm using RHEL 5.4

Does this have anything to do with cron? i.e. are you using the cron daemon for anything?

I see a whole raft of related threads using Google - surely there must be SOME useful information in all those pages.

One such page indicated that restarting the cron daemon will get rid of the errors. I did not read enough to find out WHY this helps, or what exactly causes the problem, but try restarting the cron daemon and see if the problem goes away.

If that does not help, use Google -- trust me, you are not the only one who has had this issue, and there is a LOT of stuff returned by Google.


Oh, P.S. - for future reference, it is not in your best interest to bump your thread 1.5 hours after having posted it, unless you have a bunch of valuable information to add to it. Simply asking "can anyone please help .." only serves to remove your thread from zero-replies, for no reason. Try to either wait 24 hours before considering altering your thread, or edit the original post to add more information.

pam_seos belongs to CA eTrust Access Control which is a commercially licensed product. If you have a license then you may be entitled to support. So I suggest contacting your vendor, reseller or local dealer first.
