Crowd username changes - impact on sonar-pmd plugin

[mos9mu]

Dear Sir or Madam,

I am reaching out to you on behalf of the SonarQube Team. We are using this plugin in our SonarQube EE v9.9. We authenticate to SonarQube via Atlassian Crowd. The team is about to perform a large-scale change of usernames in Crowd across the entire user base, i.e, all usernames in Crowd will be moved to different IDM system. For example, a username like "john.doe" in Crowd will be moved to "DOJ1MU"  which is based on the IDM system we are moving to. Naturally, the team would like to understand the impact this has on your plugin, the data it stores and it uses.

In more detail, we would like to understand how your app references the users in the database. Do you go with the username, which can be updated for a specific user, or do you reference the internal user key/ID. For example, in Jira, this is the app_user.user_key column. Of course, it would be of major interest whether we can expect sound handling of the change of usernames.

For reference's sake, here are two impact examples from Jira and Confluence:-

•    JRASERVER-70685: Renaming the user should also update filters and mentions •    CONFSERVER-82873: Updating the username breaks user macros

At the time of writing, this plugin version in use is v3.4.0. A quick feedback would be most highly appreciated.

Looking forward to your feedback!
