[midPoint] New user: livesync ERROR, reconciliation OK

[Wojciech Staszewski]

Hello,

I have 389ds resource as my primary user database. This is a first place where new users appear.
I configured tasks: Reconciliation and LiveSync.

Reconciliation goes OK always.
LiveSync goes OK until new user appear in LDAP, then it stops with Fatal Error:

IllegalStateException: Attempt to get single value from property {http://midpoint.evolveum.com/xml/ns/public/common/common-3}value with multiple values

Log:

java.lang.IllegalStateException: Attempt to get single value from property {http://midpoint.evolveum.com/xml/ns/public/common/common-3}value with multiple values


How to know what "value" is causing error?
I revieved my connector settings, schema, mappings and the account on the resource and the only multi-valued attribute is "memberOf", as every new user is auto-added to some groups.
