Getting "http error 401-unauthorized:invalid username or password error" while trying to register system

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux
  • Red Hat Subscription Management (RHSM)

Issue

  • While registering the client machine to the customer portal using the subscription-manager register command, it fails with the below error:

    # subscription-manager register --username "xxxxxx"--password  "xxxxxxxx" 
Registering to: subscription.rhsm.redhat.com:443/subscription
HTTP error (401 - Unauthorized): Invalid username or password. To create a login, please visit 
https://www.redhat.com/wapps/ugc/register.html

    or,

    # subscription-manager register
Registering to: subscription.rhsm.redhat.com:443/subscription
Username:*******
Password:
HTTP error (401 - Unauthorized): Invalid user credentials

  • Getting invalid username or password while trying to register the system with RHSM.

Resolution

  1. To successfully register the system with subscription-manager (RHSM), ensure the password does not contain spaces or special characters. If the password includes any, reset it here with a password that does not contain any spaces or special characters.

  2. Clear the subscription-manager data and re-register the system using the following commands:

    # subscription-manager clean
# subscription-manager register
# subscription-manager attach --auto

    After registering check if yum working:

    # yum clean all 
# yum repolist

  3. Ensure Login ID/User ID is used instead of Email Address to register RHEL machine.

Root Cause

  • Subscription-manager (RHSM) does not honor the value when a blank space or special character is added to a password.

Diagnostic Steps

  • Verify if the password contains blank space or special character.

  • Check if Email Address is used to register system instead of Login ID.
