Issue Summary

We store the SAML ID for the users when they first log in with the SSO. In some situations if the user's email address is updated to another domain and if they log in with an old account then the email address will be reverted back due to Just In Time provisioning. This is because the SAML ID is not removed when the email address is updated. 

Expected Results

Automatically clear the SAML ID when the email address is updated. 

Actual Results

SAML ID remains intact with the Atlassian Identity.

Workaround

Reach out to the Atlassian Support Team to perform SAML Delinking.
