SetupUserDBService - migrate UserRoles

[rsoika]

Currently we set the following user roles in imixs-office-workflow

• IMIXS-WORKFLOW-Manager
• IMIXS-WORKFLOW-Editor
• IMIXS-WORKFLOW-Author
• IMIXS-WORKFLOW-Reader

This generates extra complexity in setting up a security realm in app severs (wildfly and payara)

These roles need to be replaced by the core roles:

• IMIXS-WORKFLOW-Manager => org.imixs.ACCESSLEVEL.MANAGERACCESS
• IMIXS-WORKFLOW-Editor => org.imixs.ACCESSLEVEL.EDITORACCESS
• IMIXS-WORKFLOW-Author => org.imixs.ACCESSLEVEL.AUTHORACCESS
• IMIXS-WORKFLOW-Reader => org.imixs.ACCESSLEVEL.READERACCESS

Todos

Implement a new method migrateUserRoles(). This method should iterate over all existing user profiles and replace the roles.
After that the method can call

updateUser(profile);
documentService.save(profile);	

to update the user role tables and store the new txtGroups

The migration method should add the new roles to avoid braking down existing data. The method updateUser must validate the new group names!

Empty Passwords
Empty passwords are no longer supported by wildfly. We generate random passwords instead
