Cannot configure LDAP Identity Source using own URL containing a single-digit in the top-level domain. Error: Please enter a valid URL.

Products

• VMware vCenter Server

Issue/Introduction

• While adding Identity Source (Open LDAP or AD over LDAP), own URL domain with single-digit in the top-level domain (TLD) cannot be used because the URL validation fails.
• Primary server URL address contains numeric character. Example: <domain-name>.a1.
• It does not matter if the digit is at the beginning at the middle or at the end of the top-level domain (TLD),
• "Please enter valid URL" warning observed, and the browser does not have an option to proceed.

Environment

• VMware vCenter 7.x
• VMware vCenter 8.x
• VVF 9.0/9.1

Cause

• This is an expected behavior.
• Single-digit TLD (Top-Level Domain) is not supported.

Resolution

• The vSphere (HTML5) client will continue to deny single-digit TLD.

Workaround:

• The Flex, CLI, and API's do not explicitly validate single-digit TLD, so it may be possible to configure an Identity source using one with this method.
