Ticket #2015102921000361

With 1400 groups the connector results in an endless loop:

29.10.2015 17:10:59,105 LDAP        (PROCESS): S4 search continues, already found 90000 objects
29.10.2015 17:10:59,800 LDAP        (PROCESS): S4 search continues, already found 91000 objects
29.10.2015 17:11:00,478 LDAP        (PROCESS): S4 search continues, already found 92000 objects
29.10.2015 17:11:01,143 LDAP        (PROCESS): S4 search continues, already found 93000 objects
29.10.2015 17:11:01,799 LDAP        (PROCESS): S4 search continues, already found 94000 objects
29.10.2015 17:11:02,401 LDAP        (PROCESS): S4 search continues, already found 95000 objects

This happens with UCS 4.0-3errata351.

Workaround:
apt-get install \
 python-univention-connector-s4=9.0.16-40.571.201508061242 \
 univention-s4-connector=9.0.16-40.571.201508061242

The problem was the changed LDAP control list. Fixed with r64993 in 4.0-3-errata.

It still needs some tests and a YAML file.

OK - 4.0-3 - stoppen connector, create 1500 users in s4, started connector
OK - merged to 4.1-0
OK - YAML
