Description stefan.bauer 2022-08-08 13:44:48 CEST 
After updating to UCS5, changes to samba shares in UCS gui have no effect.

I tried renaming the share name (removing a whitespace)

listener.log reports:

08.08.22 13:26:00.777  LISTENER    ( PROCESS ) : updating 'cn=Formulare und Vordrucke,cn=shares,dc=company,dc=gmbh' command r
08.08.22 13:26:00.777  LISTENER    ( PROCESS ) : updating 'cn=FormulareundVordrucke,cn=shares,dc=company,dc=gmbh' command a
08.08.22 13:26:00.810  LISTENER    ( ERROR   ) : samba-shares: could not read/write tmp file /var/cache/univention-directory-listener/samba-shares.oldObject (write() argument must be str, not bytes)
08.08.22 13:26:00.886  LISTENER    ( PROCESS ) : updating 'cn=FormulareundVordrucke,cn=shares,dc=company,dc=gmbh' command m

Corresponding /etc/samba/shares.conf.d/... file did not receive any change.

I can reproduce this with 3 independent UCS5 installations.

Version is ucs 5.0-2

any help is greatly appreciated.

When I uncommented the exception handling the following exception occur:

Traceback (most recent call last):
  File "/usr/lib/univention-directory-listener/system/samba-shares.py", line 115, in handler
    pickle.dump({"dn": dn, "old": old}, fd)
TypeError: write() argument must be str, not bytes

OK: samba shares can be renamed and the configuration file integrity is ensured.
OK: Code review
OK: YAML
