LDAP users experience slow NSX-T UI logins

Products

• VMware NSX

Issue/Introduction

Symptoms:

• All NSX-T versions.
• NSX-T uses LDAP directly integrated for RBAC role assignment.
• Users that are part of a large number of AD groups, either directly or through nesting experience slow UI login.
• User may be able to login but is logged out automatically after a few minutes

Environment

VMware NSX-T Data Center

Cause

Even though a user may be a direct member of a small number of AD groups, this may explode out to a large number with AD group nesting.
As part of the login process, NSX-T does a full recursive lookup of nested groups. This is expensive from a timing perspective and results in a delayed login.

Resolution

This is a known issue affecting NSX-T Data Center.

Workaround:
To avoid slow login issues due to AD nesting, VMware recommends the following configuration limits:

• Maximum group nesting depth: 3.
• Maximum number of groups a user belongs to (including nested groups): 50.

Alternatively use vIDM as an Identity Source for NSX-T.
