KB487062: Unable to connect LDAP Server due to error, "LDAP Server error (-1): Can't contact LDAP server."


Mari Sugimura

Senior Cloud Support Engineer III • MicroStrategy


This article addresses the error message "LDAP Server error (-1): Can't contact LDAP server" that may occur when configuring LDAP authentication in MicroStrategy. This issue can often be resolved by replacing the IP address of the LDAP server with its Fully Qualified Domain Name (FQDN) in the Intelligence Server configuration.

Symptom

When attempting to connect to the LDAP server, users may encounter the following error message:

LDAP Server error (-1): Can't contact LDAP server.

This error indicates that the Strategy Intelligence Server is unable to establish a connection with the specified LDAP server.

Cause

Using IP Address Instead of FQDN: If the LDAP server is specified using its IP address, it may lead to connectivity issues, especially if SSL is being used. The LDAP server's SSL certificate may not match the IP address, causing the connection to fail.

Solution

  • Open the Strategy Developer tool.
  • Navigate to the Intelligence Server Configuration.
  • Locate the LDAP Configuration section.
  • Replace the IP address in the LDAP Host Name field with the Fully Qualified Domain Name (FQDN) of the LDAP server (e.g., ldap.example.com).
