LDAP integration lets system administrators link an existing Active Directory database to the VMS (Video Management System) Media Server for access and rights management.

Use this guide to resolve common LDAP connection issues and find answers to frequently asked questions.

Test an LDAP connection

To determine whether a connection issue comes from the VMS or your LDAP environment, test basic LDAP queries outside the VMS software using a third-party LDAP tool.

Prerequisites

• Ensure the LDAP server is accessible from the Media Server over LAN, WAN, or VPN.

• Ensure you have valid LDAP credentials. Any domain user account can query the LDAP server; special permissions or Domain Admin rights are not required.

Step 1: Run a test query

Run an LDAP query from the Media Server using a third-party browser or command-line utility.

• Windows: Softerra LDAP Browser.

• Ubuntu: OpenLDAP or install the ldap-utils package and use ldapsearch.

To run a test query on Ubuntu:

1. Open your terminal.

2. Install the LDAP utilities:

   sudo apt-get update && sudo apt-get install ldap-utils

3. Run an ldapsearch query using your domain details:

   ldapsearch -LLL -x -H ldap://ad.my.domain.com:389 -s sub -D Administrator@my.domain.com -b CN=Users,DC=my,DC=domain,DC=com -w PaSsWoRd123 -o ldif-wrap=150

   Replace the sample parameters with your network settings:

   • URL: ldap://ad.my.domain.com

   • Port: 389

   • Admin DN: Administrator@my.domain.com (or CN=Administrator,CN=Users,DC=my,DC=domain,DC=com)

   • Search Base: CN=Users,DC=my,DC=domain,DC=com

   • Password: PaSsWoRd123

Example response

A successful response returns user and container details similar to this output:

dn: CN=Users,DC=my,DC=domain,DC=com
objectClass: top
objectClass: container
cn: Users

• If the test query succeeds: Proceed to Step 2: Collect server logs.

• If the test query fails: Contact your LDAP system administrator. The issue is likely related to general network connectivity or LDAP server configuration rather than the VMS.

Step 2: Collect server logs

If third-party testing succeeds but the VMS still experiences issues:

1. In the VMS, change the main server log level to DEBUG2 (VERBOSE).

2. Replicate the failed LDAP operation.

3. Collect the Media Server logs and send them to your local reseller or support team for review.
