Likewise 4.1 Release Notes


AIX 5.2 and 5.3
---------------

On AIX systems, you may need to extend the size of certain partitions in order to ensure the installer completes successfully.  To do so, use IBM's chfs command to change the partition sizes.  For example:

# chfs -a size=+200M /usr

The above command will increase the size of the /usr partition by 200 megabytes.  This should be sufficient to ensure a successful installation.

By default, AIX is not configured to support long user and group names, which might present a conflict when you try to log on with a long Active Directory username. To increase the max username length on AIX 5.3, use the following syntax:

# chdev -l sys0 -a max_logname=MaxUserNameLength+1

Example:

# chdev -l sys0 -a max_logname=255

This command allocates 254 characters for the user and 1 for the terminating null.

The safest value that you can set max_logname to is 255.

You must reboot for the changes to take effect:

# shutdown –Fr

Note: AIX 5.2 does not support increasing the maximum user name length. 

Long username support was added to AIX 5.3. On AIX 5.2, the passwd program truncates the username to 8 characters. 

The Likewise passwd program located by default in /opt/centeris/bin does not truncate the username. There is a known issue with Likewise's password change utility. If you change a domain account password, the display name will be incorrect during the password change. However, the password change occurs correctly with the domain user that is logged in.
