![Olivier Mehani](/assets/img/avatar_default.png)
This prevents cryptic messages such as the following, from `user_ldap`: Could not set avatar for uid=user,ou=People,dc=example,dc=net, because: Signed-off-by: Olivier Mehani <shtrom@ssji.net> Add message to NotPermittedException thrown from Files\Nodes\Folder Ditto. Don't use translation macros here as this seems to be pretty low-level errors that generally get caught and prettified, and I don't want to unduly clog down the lower layers. Signed-off-by: Olivier Mehani <shtrom@ssji.net> fixup! Add message to NotPermittedException thrown from Files\Nodes\Folder
