Unable to Sign Up or Add a New User
Adding a new user to Confluence returns a stack trace:
com.atlassian.core.exception.InfrastructureException: com.atlassian.user.EntityException: Was unable to create user [zedyap] but the credentials provider [bucket.user.providers.CachingCredentialsProvider@10e7264] did not say why.
Also, public sign up fails due to this error.
Confluence user management is delegated to JIRA logins. Confluence has read-only access to JIRA database, hence, the user addition fails.
There is a request at CONF-11917 to fix the misleading error message.
Add the new user in JIRA instead. To avoid the misleading error message:
- Turn on the External User Management option. Note that, however, there is a bug in version 2.9.3 onwards that does not prevent users and groups creation.
