Maximum number of groups a user can be a member of

[Mark Treen_1]

Guys

Is there a maximum number of groups any user can be a member of and if so, can this parameter be changed?

I promise all I have tried and researched to find an answer on this but just cant....

Can you help a desperate man?

Cheers

Mark

Ask the bix itself.

getconf NGROUPS_MAX

although I'm sure that someone will take the easy approach and tell you 20.

By the way, this is a hard-limit and cannot be increased (well, unless you are HP).

Hi Mark:

The maximum value is defined by 'NGROUPS_MAX' in '/usr/include/limits.h'. In the absence of full source code you couldn't begin to change it.

If you're using NFS/RPC you can only be a member of 16 groups othewise you'll get an authentication error.
