Unable to Change User's Group

The sgroup attribute determines the lnode's parent in the scheduling tree. This hierarchy is used to regulate resource usage and to schedule the CPU. For this reason several security precautions are placed on modifying the sgroup attribute, both to avoid inadvertent errors when changing it and to prevent circumvention of Solaris Resource Manager.

To modify the sgroup attribute, a user needs one of the following privileges:

• Be the superuser

• Have a set uselimadm flag

• Have a set admin flag and be a group header for the lnode being changed

Orphaned lnodes cannot be made parents of other lnodes. See Orphaned Lnodes.
