We are going to change the authentication of our JIRA from LDAP to Shibbolized Crowd. For that all usernames must be appended with the domain. Which tables in the database contain usernames? (Or could this be done with API?)
We have done this before with an old version of Confluence that needed about 15 tables to be updated. Current version of Confluence should be much easier and JIRA should not be very hard, either.
