PAM error: PAM unable to dlopen(/lib/security/pam_vas3.so)

Hello,

In recent days, a server is installed QAS will not let me login.

checking logs in /var/log/messages, the following appears:

Sep 7 9:54:22 mutis2 su: PAM Unable to dlopen (/ lib/security/pam_vas3.so)
Sep 7 9:54:22 mutis2 su: PAM [dlerror: / lib/security/pam_vas3.so: undefined symbol: pam_vas_cleanup_user_state]
Sep 7 9:54:22 mutis2 su: PAM Adding faulty module: / lib/security/pam_vas3.so

With a local user I can login but with a user in Active Directory / LDAP I can't.

I have reinstalled QAS client but the problem persists .

Can anyone help me?

P.D: The server is a Fedora Core 4
