Configuring LDAP server discovery using DNS SRV records

Last Updated : Jun 10, 2026 |

About this task

Avaya Aura® Device Services can discover your LDAP server instances using DNS SRV lookup. On the Avaya Aura® Device Services web administration portal, you can provide a domain name instead of an IP address or FQDN of the LDAP server. Avaya Aura® Device Services discovers all available LDAP server instances associated with this domain using SRV records.

Avaya Aura® Device Services determines which LDAP server to use based on the priority and weight configured in SRV records for the servers.

Before you begin

  • Ensure that a search or domain entry of the /etc/resolv.conf file contains the domain name for which you want to discover LDAP server instances.

  • On your DNS servers specified in the /etc/resolv.conf file, configure SRV records for each LDAP server that needs to be discoverable using SRV records. If you have multiple LDAP servers instances, configure an SRV record for each LDAP server instance.

Procedure

  1. On the Avaya Aura® Device Services web administration portal, navigate to Server Connections > LDAP Configuration > Enterprise Directory.
  2. Select the appropriate LDAP server.
  3. Select the Use DNS check box.
  4. In Address, type the following:

    _<SERVICE>._tcp.<DOMAIN_NAME>

    In this entry:

    • <SERVICE> is one of the following symbolic names for the LDAP service:

      • ldap: If you use the standard LDAP connection to the LDAP server.

      • ldaps: If you use the secure LDAP connection to the LDAP server.

    • <DOMAIN_NAME> is the domain name for which you want to discover LDAP server instances.

    For example, if you use the secure LDAP connection to the server and the domain name is example.com, type the following:

    _ldaps.tcp.example.com

  5. Click Save.

Next Steps

Test the connectivity to the LDAP server.
