This typically happens when Active Directory (AD) SSO was enabled for 360Suite and the default login URL (http[s]://<server>:<port>/360.suite/login) is being used.
As per our documentation about AD SSO configuration (see
here), the proper URL to use when 360Suite was configured with AD SSO is the full URL with page format extension (.xhtml):
- http[s]://<server>:<port>/360.suite/login.xhtml
If AD SSO was enabled and you exceptionally don't intend to use it, then the page "logonNoSso.xhtml" should be used so the AD SSO configuration remains:
- http[s]://<server>:<port>/360.suite/logonNoSso.xhtml
These URL formats follow the same logic as SAP BusinessObjects' logic with AD SSO configuration.
