DNS: SRV Record

[BlackJack01090]

Hello,

I want to set up a PDC. If the client want to join the Domain I become an error of an missing SRV Record. So I tried to set a SRV Record in ISPConfig 3. I get the error that the Record need three text strings. I dont't know why. Should the Record looks like this?

_ldap._tcp.example.com. 3600 IN SRV 10 0 389 ldap01.example.com.

Where are the three text strings?

Sorry for my englisch

Greetings
