対策
1. Ensure the DNS server that TPAM is configured to use can resolve all the SRV LDAP records for the Domain Name (eg. SRV _ldap._tcp.yourdomain.com ) that is specified on the Systems "Connection" tab2. Ensure TPAM is able to communicate to the all of the returned servers using LDAP TCP/389 and CLDAP UDP/389
