16.04, wrong units start order

[sles]

Hello!

squid uses ldap and mysql for authorization , so I added them to squid dependencies:

### BEGIN INIT INFO
# Provides: squid
# Required-Start: $network $remote_fs $syslog mysql slapd

After=systemd-journald.socket basic.target systemd-journald-dev-log.socket mysql.service remote-fs.target network-online.target nss-lookup.target system.slice sysinit.target slapd.service

And symlinks are created in right order:

S03slapd
S04mysql
S05squid

But really squid is started before mysql (mariadb) and slapd are started:

journalctl -u squid
-- Logs begin at Ср 2016-07-06 13:10:30 SAMT, end at Ср 2016-07-06 13:44:41 SAMT. --

journalctl -u slapd
-- Logs begin at Ср 2016-07-06 13:10:30 SAMT, end at Ср 2016-07-06 13:45:36 SAMT. --

journalctl -u mysql
-- Logs begin at Ср 2016-07-06 13:10:30 SAMT, end at Ср 2016-07-06 13:45:46 SAMT. --

июл 06 13:10:43 inetgw2 mysql[2647]: * Starting MariaDB database server mysqld

i.e. real start order is:
sqiud
slapd
mysql

Expected result is folowing
slapd
mysql
squid

Excellent result :-)
