CVS commit: src/usr.bin/id

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Tue Aug 30 16:47:47 UTC 2005

Modified Files:
        src/usr.bin/id: id.c

Log Message:
id(1) didn't check the return value of getgrouplist(3) and used memory
outside the group array in the case that a user is member of more than
_SC_NGROUPS_MAX groups.
(This is probably also the problem behind PR bin/31069 by Zafer Aydogan.)
So check the return value and retry with sufficiently allocated memory
in case the initial _SC_NGROUPS_MAX groups are not enough.
