After installing the LKP, Linux user logins and groups are automatically created in the Linux environment for all existing UnixWare 7 users.
You can add, delete or modify user logins or groups from either UNIX or Linux mode. The commands are linked so that you are always using the UnixWare 7 version of a command, regardless of the mode you are in.
User and group management-related files are linked so that updates are reflected in both environments. Linked files include:
``The File Update Daemon'' monitors link integrity for these files and automatically restores broken links, if necessary. This is useful because some applications bypass the standard user and group management interface (useradd/usermod/userdel, groupadd/groupmod/groupdel) and use their own file locking mechanism. This can destroy the symbolic links for the files being manipulated.
The FUD detects broken links and re-links the files properly, but it throws out any changes that were being made when the link was broken. You can review /var/adm/syslog to see the rejected changes. If users were being added or passwords changed when the link was broken, you can add the required users and passwords from the command line using useradd(1M).
