Administering user accounts

Changing the limit on simultaneous group membership

The maximum number of groups that a user can be in at one time is 8 by default. There are no warning messages displayed when this number is exceeded, but when the sg(C) command is used to extend a user's group list using the verbose option (-v), this error message is displayed:

   sg: unable to add group group as supplemental group list full
This limit is controlled by the NGROUPS tunable kernel parameter. To change this value, use the Hardware/Kernel Manager or the configure(ADM) command. Select category 7, ``User and group configuration'', then change the value of NGROUPS. The kernel must then be relinked and booted for the new value to take effect. See ``Rebuilding the kernel'' for more information.
