I am using Centos5 running on a VMWare but whenever I choose to open the User Manager menu from System->Administration, an error message always displays
The user database cannot be read. This problem is most likely caused by a mismatch between etc/passwd and /etc/shadow or /etc/group and /etc/gshadow/. The program will now exit.
I am a Linux novice and have no idea how to fix this tiny issue. ANy help is thankful. Thank you.
