if you can get the result in a variable, then you can use
transformations to get the value of 'ou' -- hope i understood correctly
what you need:
http://www.kamailio.org/dokuwiki/doku.php/transformations:1.5.x

Problem was my misunderstanding of LDAP concept. The answer is that 'ou' is attribute of user and can be fetched to kamailio variable as usually.
