- Validation
-
Yes. If
ngroups_max
is set to an invalid value, it is automatically reset to the closest legal value. For example, if it is set to less than zero, it is reset to 0. If it is set to greater than 1024, it is reset to 1024. - When to Change
-
Review the following considerations if you are using NFS
AUTH_SYS
authentication and you want to increase the defaultngroups_max
value:-
If
ngroups_max
is set to 16 or if the NFS client'sAUTH_SYS
credential that is provided has 15 or fewer groups, the client's group information is used. -
If
ngroups_max
is set to greater than 16 and the NFS client'sAUTH_SYS
credential from the name server contains exactly 16 groups, the maximum allowed, the NFS server consults the name server and matches the client's UID to a user name. Then, the name server computes a list of groups to which the user belongs.
