Problem Definition

In Bitbucket Server 5.5 personal access tokens have been introduced. They can be used to replace passwords over https, or to authenticate using the Bitbucket Server REST API over Basic Auth. However the tokens cannot be used for administrative access REST endpoints like /rest/access-tokens/latest/users/admin or
/rest/api/1.0/admin/permissions/groups

The error message: Tokens may not have the following permission: ADMIN

Suggested Solution

Please provide the access tokens with the global ADMIN permissions.

Why this is important

Using tokens for the system management automation is more comfortable and secure rather than login-password authentication.
