9.7. Verifying the trust configuration on IdM

Procedure

1. Run a DNS query for the MS DC Kerberos over UDP and LDAP over TCP service records.

   [root@server ~]# dig +short -t SRV _kerberos._udp.dc._msdcs.idm.example.com.
   0 100 88 server.idm.example.com.
   
   [root@server ~]# dig +short -t SRV _ldap._tcp.dc._msdcs.idm.example.com.
   0 100 389 server.idm.example.com.

   These commands list all IdM servers on which ipa-adtrust-install has been executed. The output is empty if ipa-adtrust-install has not been executed on any IdM server, which is typically before establishing the first trust relationship.

2. Run a DNS query for the Kerberos and LDAP over TCP service records to verify that IdM is able to resolve service records for AD:

   [root@server ~]# dig +short -t SRV _kerberos._tcp.dc._msdcs.ad.example.com.
   0 100 88 addc1.ad.example.com.
   
   [root@ipaserver ~]# dig +short -t SRV _ldap._tcp.dc._msdcs.ad.example.com.
   0 100 389 addc1.ad.example.com.
