Fix inconsistent passwd compensation in nss/bug17079.c
|
||
|
|
|
||
|
|
It used to be common practice to have a statically linked shell for an
|
||
|
|
alternative root account, as in:
|
||
|
|
|
||
|
|
root:x:0:0:root:/root:/bin/bash
|
||
|
|
toor:x:0:0:root recovery account:/root:/sbin/sash
|
||
|
|
|
||
|
|
This causes problems with passwd NSS tests because a UID-based lookup
|
||
|
|
will only retrieve one of those entries. The original version of
|
||
|
|
nss/bug17079.c detected this, but failed to use this information later
|
||
|
|
on.
