Hello, i've tested your case on our test installation (12.5 and WHMCS 6).
First of all, i've created a customer with subscription in WHMCS and tried to provision to Plesk.
Next, i've created a second domain for this customer.
Next I was going to 'Services' -> 'My services' after i logged in as client. There were a two subscriptions. I pressed view details for both of them. Link 'Open Control Panel' was on every details page and i successfully logged in from every page.
Next i was going to Admin interface and see 'Module log' (Utilities -> Logs -> Module logs). There were a following calls:
<?xml version="1.0" encoding="UTF-8"?><packet version="1.6.3.5"><server>
<create_session>
<login>testuser</login>
<data>
<user_ip>MTAuNTAuMS43OA==</user_ip>
<source_server>MTAuNTAuMS43OA==</source_server>
</data>
</create_session>
</server></packet>
<?xml version="1.0" encoding="UTF-8"?><packet version="1.6.3.5"><customer>
<get>
<filter>
<external-id>whmcs_plesk_34</external-id>
</filter>
<dataset>
<gen_info/>
</dataset>
</get>
</customer></packet>
<?xml version="1.0" encoding="UTF-8"?><packet version="1.6.3.5"><server>
<create_session>
<login>testuser</login>
<data>
<user_ip>MTAuNTAuMS43OA==</user_ip>
<source_server>MTAuNTAuMS43OA==</source_server>
</data>
</create_session>
</server></packet>
<?xml version="1.0" encoding="UTF-8"?><packet version="1.6.3.5"><customer>
<get>
<filter>
<external-id>whmcs_plesk_34</external-id>
</filter>
<dataset>
<gen_info/>
</dataset>
</get>
</customer></packet>
These calls means that first of all we asks Plesk about user with exterrnal id 'whmcs_plesk_34' and then we create a session for him. As you can see, we have a one user for both domains. So, i couldn't reproduce your problem.
Is the any additional steps to reproduce? As solution i propose to you to contact with Odin Support for a deep investigation.
