Description Stefan Gohmann univentionstaff 2012-01-11 16:16:07 CET 
Bei den automatischen S4 Connector Tests bekomme ich nach einiger Zeit für alle LDB Operationen den folgenden Traceback:

Comment 1 Stefan Gohmann univentionstaff 2012-01-12 06:56:28 CET 
Scheinbar tritt das Problem auf, wenn ich versuche den gleichen Benutzer in unterschiedlicher Groß-/Kleinschreibung hinzufügen, hier 'CN=sgwwqxyk,CN=Users,DC=deadlock64,DC=local' und 'cn=sgwwqxyk,cn=users,dc=deadlock64,dc=local'.

Da das nur durch einen S4 restart behoben werden kann, sollten wir das in 3.0-1 beheben.
Comment 2 Stefan Gohmann univentionstaff 2012-02-09 15:14:29 CET 
Bisher ist das in sehr vielen weiteren Tests nicht erneut aufgetreten.

Nach dem Neustart von samba4 und dem connector ging es dann weiter
Comment 4 Felix Botner univentionstaff 2012-06-01 10:33:16 CEST 
Created attachment 4424 [details]

Comment 5 Stefan Gohmann univentionstaff 2012-07-09 13:32:21 CEST 
Das sollten wir mit dem nächsten Samba4 Upstream Import nochmal prüfen.
Comment 6 Stefan Gohmann univentionstaff 2012-10-15 07:23:13 CEST 
Ich kann das Problem mit der S4 Version in UCS 3.1 nicht mehr reproduzieren.
Comment 7 Tobias Peters univentionstaff 2012-10-19 14:03:15 CEST 
Nach vielen Durchläufen der Tests ist es auch bei mir nicht mehr aufgetreten.
Comment 8 Stefan Gohmann univentionstaff 2012-12-12 21:08:23 CET 
UCS 3.1-0 has been released:
