​
Limitation (Authentication Error)

Even with the correct ID and password, an authentication error can occur and the integration can fail. If you see an authentication error, check whether your situation matches any of the cases below.

​
Unsupported Integration Methods

Integration fails if any condition below applies and this service requires ID/password authentication for that SaaS.

​
Cases Where Connection is Possible

Even in SSO environments, integration is possible if direct ID/password login is also available.
  • SSO is disabled for administrator accounts only
SSO is enforced for regular users, but direct login is permitted for administrator accounts.
  • External IdP and direct login can be used together
Even when external IdP integration is the primary method, direct sign-in via ID/password fields may still work.

​
Workarounds

Even when SSO or an external IdP is enforced, integration may still be possible with the steps below. Prepare an administrator account that can log in with an email address and password.
  • Set a password for the account on the cloud service side.
  • If you cannot set a password for the account, create a dedicated “system integration account” on the cloud service side. Use that account to set up the integration.
