It is listed in the case materials; the current Solaris kernel will drop any RPC operation where the user is in more than 16 groups. Other implementations will just truncate the number of groups to 16. I'm inclined to follow the market, truncate the group list and then try the RPC operation. It's in the specification. Specifically, I was convinced when I was running with 1000 groups and I was not able to access anything over NFS. Not very practical. Casper
