Max Groups

[bfitzmai]

Is there anyway to change the maximum number of groups I can be a member of. By default, the number is 17 on Solaris 2.6

Thanks
Bruce

this is, what I stole ;-) from sunsolve.sun.com

DOCUMENT ID: 01247 

SYNOPSIS: Maximum number of supplementary groups per user 

...some more info...

The NGROUPS_MAX value defaults to 16, and the absolute maximum is 32. The default value can be reset as follows: 


Edit the /etc/system file and add the following line: 
set ngroups_max = 32

Reboot the system. 

Verify that NGROUPS_MAX has been set to the correct value after rebooting using the getconf command. 

# getconf NGROUPS_MAX
32

Note: Do not raise the value of NGROUPS_MAX above 16 for systems that need to be NFS clients as this will break NFS authorization and those users will not be able to login because NFS internally depends on NGROUPS_MAX and is limited to only 16. 

Also, while booting up, the following message is displayed on the console: 

WARNING: ngroups_max of 32 > 16, NFS AUTH_SYS will not work properly

Thanks Franz...
I guess I am stuck with 16. The MFS client issue is the
killer.
