    Handle ldap size limit exeeded exception

    LDAP servers have sizelimit configuration to limit the number of
    user/group objects that can be returned for an LDAP query. This
    change catches the size limit exceeded exception when users/groups
    returned from ldap search query exceeds the configured limit and
    responds with an appropriate error message instead of default
    500 error message.
