Description
Issue Summary
When a Space is imported from Cloud to Server, the import logic compares user "lowerName" from Space XML with "lower_email_address" from cwd_user. When it finds more than one record for that email adress with different "lower_user_name" it marks it as Ambigous. Then it tries to create to create a new record on user_mapping. In case already exist a user on user_mapping using theat email as username it will fail.
Steps to Reproduce
- In Confluence server have multiple users (different "lower_user_name") on cwd_user but same "lower_email_address", and one of them has "lower_user_name" equals to user "lowerName" from Space XML:
user_name lower_user_name lower_email_address external ID Directory ID admin admin user@example.com 937c9532-f12f-437b-a8fd-7e9e0e8d8e69 294913 example example user@example.com 86782f67-5bc1-4818-9326-a9bc63eeccb3 8126465 user@example.com user@example.com user@example.com 458af6bc-40ae-49ae-9dff-7528d854836e 8126466 - user_mapping table has a record with a username equals to user "lowerName" from Space XML:
user_key username lower_username 402880847157f278017157f699530000 user@example.com user@example.com - Import a Space from Cloud where one of the users "lowerName" is equals to a "lower_email_address" and "lower_user_name" on cwd_user and already have a record on user_mapping:
Cloud's XML export
<object class="ConfluenceUserImpl" package="com.atlassian.confluence.user"> <id name="key"><![CDATA[8a7f808564e27fae0164d4db118d0064]]></id> <property name="name"><![CDATA[user@example.com]]></property> <property name="lowerName"><![CDATA[user@example.com]]></property> <property name="atlassianAccountId"><![CDATA[5a0bbaa80e8b4605b373d809]]></property> </object>
Expected Results
Confluence should recognise that the imported user already exist on cwd_user using "lower_user_name" to avoid mark it as Ambigous, and use the user_mapping record to reference the content.
Actual Results
During the import, will mark user as Ambiguous, the error below can be seen in the atlassian-confluence.log:
2022-09-30 19:22:19,778 WARN [Long running task: Importing data] [importexport.xmlimport.persister.ConfluenceUserPersister] persist Ambiguous result while trying to match user by email address.

Confluence will try to add a new row (user) into user_mapping which will eventually result into violation of the unique constraint on user_mapping.lower_username, as record already exists:

Workaround
- Identify the user record that is in User, temporaly change the email addresses of the of other records. It can be done by UI if users are from Internal User Directory or by LDAP.
- Import Spaces again
- Change emails address back
