[midPoint] ConnectorServer AdLdapConnector Exceptions

[Patrick Spengler]

​Hello,

we have the following ConnectorServer setup:
midpoint(3.9) -> connector-server(1.5.0.1) -> AdLdapConnector(2.2) -> Ad (2012 R2)
The AdLdapConnector is configured with Domain-Admin.

We can create Accounts on ad. 
But if we modify the Account in midpoint (e.g. Activation disable), 
we get the following Exceptions:
