when using mysql -> LDAP, numeric results in mysql cause errors

[styx-tdo]

Query for "mailUidNumber" which is integer:

Nov 07 08:30:36 - ERROR - Error while adding entry uid=10221,xxxxxxxxxxxxx,dc=xx in directory :javax.naming.directory.InvalidAttributeValueException: Malformed 'mailUidNumber' attribute value; remaining name 'uid=10221,xxxxxxxxxxl'

When I change the underlying view to:

cast(`mail_user`.`mailuser_id` as char charset utf8mb4) AS `mailUidNumber`,

this works as expected.

lsc should not be dependent on the column type of the database.

REPRODUCE:
Create a mysql table with mailuser_id as an int(11)

Sync that to ldap
