Linux Groups
Hi All,
How many secondary groups can a user belong to in Linux. I read something about 15 secondary groups,could somebody confirm ?
I see some users are part of more than 30 secondary groups.
Thanks,
Raja

Re: Linux Groups
To see the kernel's limit, run "getconf NGROUPS_MAX". On my Linux, it says "65536" so the kernel has no problems with a large number of groups.
If you use NFS, the NFS protocol version 3 or earlier can handle a maximum of 16 groups (=1 primary + 15 secondary groups) per user.
This is a NFS protocol limitation that impacts all OSs that use NFSv3 or earlier, not only Linux.
