Don't add input group during initgroups_dyn in hesiod
|
|
|
|
Fixes BZ #15304.
|
|
|
|
The *initgroups_dyn functions are called with a group argument. This
|
|
group gid is usually skipped while populating the grouplist since the
|
|
caller adds that group id in advance.
|
|
|
|
The hesiod initgroups_dyn implementation however adds the group gid to
|
|
the list if it does not already exist. While it works fine for the
|
|
usual initgroups, it breaks nscd since it calls initgroups_dyn with -1
|
|
as the gid (to have all groups included).
