A new glibc feature allowing to merge domain groups with local groups

[Uri Simchoni]

If I read this correctly, this patch seems to encourage the use of 
gr_mem memberlist. IMHO gr_mem should be deprecated in favor of 
getgrouplist(). Samba for example doesn't use gr_mem at all, but it uses 
getgrnam() often just for name->id translation. Think of the cost if a 
group has thousands of users. And you can't turn it off per-application.

The getgrouplist() plugin interface supports merging (albeit in a kind 
of undocumented and hackish way) because a "continue" will give next 
plugin the previous plugin's list of groups to which it can append its 
own list.

Uri.
