ngroups_max

Description

The ngroups_max parameter specifies the maximum number of multiple groups to which a user may simultaneously belong.

The constants NGROUPS_UMIN <= ngroups_max <= NGROUPS_UMAX are defined in </usr/include/sys/param.h>. NGROUPS_UMIN is the minimum number of multiple groups that can be selected at lboot time. NGROUPS_UMAX is the maximum number of multiple groups that can be selected at lboot time and is the number of group-id slots for which space is set aside at compile time. NGROUPS, which is present for compatibility with networking code (defined in </usr/include/sys/param.h>), must not be larger than ngroups_max.

Value

Default: 16

Range: 0-32

When to Change

The default value is adequate for most systems. Increase this parameter if your system has users who need simultaneous access to more than 16 groups.
