Subject: [PATCH 3/6] smbpasswd: remove root-related restrictions
|
|
|
|
* Allow -L to work when non-root
|
|
* Allow deleting and renaming of user with uid = 0
|
|
A good sanity check, indeed, but when getpwnam etc. is modified
|
|
to return a passwd entry for root only, then this poses a problem...
