is there a group limit for NFS exported file systems in recent kernels?
One if my users cannot access directories that belong to a group he
actually _is_ a
member of. That, however, is true only when accessing them over NFS. On
the local file
system, everything is fine. UIDs and GIDs are the same on client and
server, so that
cannot be the problem. Client and server run Gentoo Linux with kernel
2.6.16 on the
server and 2.6.17 on the client.
Is he a member of more than 16 groups?
Yes. He is actually a member of 27 groups.
Is the limit of 16 groups still current? I was under the impression that it is a limitation of 2.4 kernels....
Is there any proper work-around for this?
The 16 group limit is defined by the specification for AUTH_SYS for the RPC.
It can not be easily changed without affecting interoperability.
The use of RPCSEC_GSS and Kerberos can remove this limit.
Thanx...
