Infrastructure Manager login failure to Hub 23.4.4 - Unknown Error or Password Expired

Products

DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

When trying to log in to a secondary hub running version 23.4.4 (CU4) via Infrastructure Manager (IM), the login fails with these symptoms:

Note: IM logins work fine on hubs running CU1 through CU3.

IM CU1 / CU3: Pop-up says, "Login failed. The username or password is incorrect. Letters must be typed using the correct case. Ensure Caps Lock is not accidentally on."
IM CU4 or higher: Pop-up says, "Reset Password Message – Your password has expired. Click the Reset button to reset it."
nimbus_manager.log shows: nimLogin request login failed – unknown error or Your password has expired. Please contact your administrator.
Hub.log shows: Login failed for administrator, IP = <IP_Address>, as password has expired.

Environment

DX UIM: 23.4.1 (CU1) through 23.4.3 (CU3)

Hub Probe: 23.4.4 or higher

Infrastructure Manager: Versions prior to 23.4.4

Cause

Starting with hub probe version 23.4.4 (CU4), DX UIM introduced a mandatory password policy and a default 90-day expiration for local Nimbus accounts.

Complexity Requirements: Passwords must now have at least 8 characters, including one uppercase letter, one lowercase letter, one digit, and one special character.
Client Incompatibility: Older versions of the Infrastructure Manager FAT client do not support the new password reset challenge workflow. When the hub rejects a login because the password is expired or non-compliant, the older IM client cannot process the reset request and returns a generic failure or incorrect password error.

Resolution

To resolve the login issue on your secondary hub, the administrator password must be updated on the primary hub and allowed to replicate.

1. Back up security files

On the Primary hub, back up the current security files by copying all files matching <Nimsoft>\hub\security.* to a safe backup folder.

2. Change the administrator password.

Log in to Infrastructure Manager (IM CU1/CU3) as the administrator. Go to Security → User Administration.

Select the administrator account, right-click, and choose Edit User. Click Set Password and enter a new password that meets the following complexity requirements:

At least 8 characters
Minimum 1 uppercase letter
Minimum 1 lowercase letter
Minimum 1 number
Minimum 1 special characterr

Save and apply changes:

Click OK in both the Set Password and Edit User menus, then close the User Administration menu to save the changes.

3. Verify the Primary hub login:.

Exit IM completely, reopen it, and log in to the Primary hub using your new password to verify it works.

4. Allow replication:

Wait approximately 10 minutes for the updated security configuration to automatically replicate to the rest of your environment before testing the login on any secondary hubs.
