• Overcloud deploy is failing with:

TASK [tripleo-keystone-resources : Assign admin role to admin project for admin user] ***
Monday 21 March 2022  12:03:48 +0000 (0:00:07.808)       0:14:34.598 **********
fatal: [undercloud]: FAILED! => {"changed": false, "msg": "HttpException: 401: Client Error for url: https://overcloud.example.com:13000/v3/users, The request you have made requires authentication."}

• Keystone commands work after sourcing overcloudrc but the deploy continues to fail with the above 401 error
