[Gluster-users] 32 group limit

[Harshavardhana]

Hey Tom,

http://review.gluster.org/7501 - this fixes your issues, its currently
on the master branch should be backported to release-3.5 branch.
Copying Niels he can explain more.

    rpc: implement server.manage-gids for group resolving on the bricks

    The new volume option 'server.manage-gids' can be enabled in
    environments where a user belongs to more than the current absolute
    maximum of 93 groups. This option triggers the following behavior:

    1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or
       libgfapi) will contain only one (1) auxiliary group, instead of
       a full list. This reduces network usage and prevents problems in
       encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes.
    2. The single group in the RPC Calls received by the server is replaced
       by resolving the groups server-side. Permission checks and similar in
       lower xlators are applied against the full list of groups where the
       user belongs to, and not the single auxiliary group that the client
       sent.
