To install the UNIX security realm
* 
Administrators must log in as root.
1. Move to the following directory:
installdir\bin
2. Make sure the correct file owner and permissions are assigned to the verify file:
chown root verify
chmod +xs verify
For Red Hat Linux, create a file //pam.d/mksunixrealm containing the following:
#%PAM-1.0
#
auth required /lib/security/pam_stack.so service=system-auth
account required /lib/security/pam_stack.so service=system-auth
password required /lib/security/pam_stack.so service=system-auth
session required /lib/security/pam_stack.so service=system-auth
For SuSE Linux, create a file //pam.d/mksunixrealm containing the following:
#%PAM-1.0
#
auth required pam_unix2.so
account required pam_unix2.so
password required pam_unix2.so
session required pam_unix2.so
3. Restart PTC RV&S Agent and log in using UNIX user IDs.

If you are administering the UNIX security realm under Linux, the verify program only needs to have setuid applied if shadow passwords are used.
