Description Arvid Requate

2017-02-02 11:42:56 CET

Created attachment 8396 [details]
improve_s4_connector_detection.diff

If Samba/AD shall be installed later on the UCS@school Master in a Multiserver environment, after UCS@school Samba/AD DC Slaves have been joined, then it is important to set these two UCR variables first:


ucr set samba4/provision/primary=yes \
        connector/s4/allow/secondary=yes

Otherwise the univention-samba4 joinscript will attempt to join into a school.

The attached patch should improve the detection of the S4-Connector, so that it "just works" and manual setting of the UCR variable is not required. This is a) good for UCS@school and b) simplifies the code a bit in both, the samba4 and the s4connector join scripts.

Package rebuilt with patch.

Advisory: univention-s4-connector.yaml

The s4 connector script now uses univention-samba4 functions which have been added. The bug number is in both YAML files, so the update will be announced at once.

It won't work if univention-samba4 is already installed in the old version.  We've have had a similar situation in UCS 4.1.

So, I think we should update the dependency.

Ok, dependency added.

Comment 4 Felix Botner

OK - normal setup s4 master + s4 slave
OK - school master + school s4 slave 
    OK + s4 on master
    OK + new s4 school slave
OK - school s4 master + school s4 slave

FAIL s4 master + s4 backup 
 * "standalone" samba on backup (should join to master)
 * s4 connector is running (should not be started, already running on master)

Comment 5 Arvid Requate

As discussed, I've replaces the ugly "samba-tool drs showrepl" detection (introduced for Bug #33399) by LDAP search filters adjusted for UCS@school.

OK - normal setup s4 master + s4 slave
OK - s4 school master + s4 school backup (joins into master, no s4 connector)

TODO - school master + school s4 slave 
    TODO + s4 on master
    TODO + new s4 school slave
TODO - school s4 master + school s4 slave

     OK + s4 on master
     OK + new s4 school slave

OK - school s4 master + school s4 slave
