Secondary groups Limit

[Amit Kureel]

What is the maximum no. of secondary groups that any user can be assigned ? Is it NGROUPS(=20) as defined in limits.h ?

From man group:
All group IDs used in /etc/logingroup or /etc/passwd should be defined
in /etc/group. No user should be associated with more than NGROUPS
(see setgroups(2)) groups in /etc/logingroup.

And, from man 2 setgroups:
setgroups() sets the group access list of the current user process
according to the array gidset. The parameter ngroups indicates the
number of entries in the array and must be no more than NGROUPS_MAX,
as defined in .
