Description

The tests in org.apache.jackrabbit.oak.security.authentication.ldap.LdapLoginTestBase#testConcurrentLogin fail because of a conflict when creating the intermediate nodes, although they are identical for all concurrent updates.

strange enough, the error is completely different:

"Cannot create user/group: Intermediate folders must be of type
rep:AuthorizableFolder."

this is reported on the "addExistingNode" parent, because the User validator traverses up the following tree:

"/rep:security/rep:authorizables/rep:users/:conflict/addExistingNode/u/us/user-5"
