Description Arvid Requate univentionstaff 2016-01-11 18:04:38 CET 
The S4-Connector should only store valid DN-relations to 'DN Mapping CON' and 'DN Mapping UCS'. In the case of Bug 40380 Comment 5 an invalid DN relation was stored and then the S4-Connector insists to use that instead of searching again. The S4-Connector should store these DN-relations only for successful synchronizations.

At least two functions rely on these DN-relation tables:

* samaccountname_dn_mapping
* dns_dn_mapping

They attempt to determine the target DN from the tables and if something is stored then it is taken as "premapped".


In addition to this approach of avoiding invalid entries it might be necessary to make the S4-Connector "forget" a premapping if a reject is encountered at some point.
