nis is deprecated as per PEP 594, so there won't be further enhancements to it.

Is this really a bug (discrepancy between nis.cat doc and behavior) or a 
feature request?

[issue2148] nis module not supporting group aliases

[Ernst Persson]

New submission from Ernst Persson:

Nis (applications?) has a line limit in the group entry, so you can't 
have very long lines (=many users)
The way to solve this is to put aliases in the group map, like this:
MY_GROUP::123:user1,user2
MY_GROUP::123:user3,user4

This is supported by the OS, grp.getgrall(), etc, but
nis.cat(group)
only puts the last entry into the dict it returns.

I guess the best thing if you want to return a dict is to merge the 
members if both the name and gid matches.

Martin v. Löwis added the comment:

Can you dig up some specification for that behaviour? The more official,
the better.

Otherwise, I'd rather add an option to return a list instead of a dict;
people wanting that semantics could then do their own processing.

Ernst Persson added the comment:

Here's another description of the issue:
http://www.tldp.org/HOWTO/NIS-HOWTO/maps.html#AEN548
There's a suggestion to have different group-names but same gids, but 
automatic splitters of nis-groups doesn't allways do this.

Right, grp.getgrall() returns a list, that's why it works.
