net.tcp.service check with ldap, always wrong

[yerrysherry]

Hey,

I try to check an ldap service. I know it's up and running but the net.tcp.service check fail always with service: ldap

./zabbix_get -s postregistratiepres-oe-1-mgt.mmis.be. -k "net.tcp.service[ldap,10.0.10.245,389]"
0

But is works with the service http

./zabbix_get -s postregistratiepres-oe-1-mgt.mmis.be. -k "net.tcp.service[http,10.0.10.245,389]"

When doing this on postregistratiepres-oe-1-mgt.mmis.be:

# telnet 10.0.10.245 389
Trying 10.0.10.245...
Connected to 10.0.10.245.
Escape character is '^]'.

Any idea?

Regards,
Gerrit

Does the directory service require TLS?
