Retrieving the user and group name length limit from the ODM database
You can use commands or subroutines to retrieve the v_max_logname parameter.
You can use the lsattr command to retrieve the v_max_logname
parameter in the ODM database. The lsattr command displays the
v_max_logname parameter as the max_logname attribute.
The following example shows how to use the lsattr command to retrieve the
max_logname attribute:$ lsattr -El sys0
