Admin Approvement fails

As an Admin I need to activate users.

This error happens, when i try to activate a user:

Call to a member function getTermsVersion() on null 

Error thrown in file
/home/mystage/ci/releases/58/html/typo3conf/ext/t3o_ldap/Classes/Connectors/Ldap.php in line 478.

We need to update to latest t3o_ldap version
