NGROUP increase - thoughts
I'm sure this has been given thought, so I want to probe teh collective resources. We need to have users in more than 32 groups. In fact, they may need to be a member of MANY more groups than that.
What is the current thinking on this problem? Would it be desirable to replace current->groups[NGROUPS] with a poibnter to an array? Thus allowing (with libc changes) many more groups?
Comments, please.

The real solution is ACLs (if you are talking filesystem permissions). See acl.bestbits.at, I think, for ext2 ACL/EA patch.
