UW supports the following single sign on (SSO) protocols:
SAML 2
CAS
OIDC/OAuth
ADFS
We do not allow direct access to Active Directory by external services.
UW is also a member of the InCommon federation (https://incommon.org). If the service you want to set up SSO for is also a member then it is quite possible access is already granted to the service without the need for further set up.
