SSO: maintain Domain Credentials not working when SSO is enabled

Content

Hi all 

we are experiencing an issue where when we have SSO enabled for EPM CLOUD users and only want to maintain the natie users connection for those users who need to use utlities such as EPMAutomate, the option does not actually work, and only the COMPANY ID login is displayed for this specific users. 

We ensured that they have Service Domain rights, but it still fails. 

Can someone please let me know if there is a bug about this right now or if I am missing something?

Here is the documentation supporting this issue:
