Notes

Renaming the username does not fix the problem.

Workaround

PostgreSQL

alter table userassociation alter column SOURCE_NAME type varchar (255);

MySQL

alter table userassociation modify SOURCE_NAME varchar(255) COLLATE utf8_bin NOT NULL;

• Always backup your database before modifying you database directly
