# Which Problems Are Solved
When using implicit flow through the session API and a login UI on a
custom domain (proxy), the tokens were signed by the API domain of the
instance, rather than the public (proxy) domain.
The SAML response had the same issue. Additionally, the saml library had
an issue and lost the issuer context. This prevented also a successful
login through the hosted login UI.
# How the Problems Are Solved
- The issuer of the SAML and Auth request is persisted to provide the
information when signing the responses and tokens.
- The SAML library is updated to the latest version.
# Additional Changes
None
# Additional Context
None
# Which Problems Are Solved
It is currently not possible to use SAML with the Session API.
# How the Problems Are Solved
Add SAML service, to get and resolve SAML requests.
Add SAML session and SAML request aggregate, which can be linked to the
Session to get back a SAMLResponse from the API directly.
# Additional Changes
Update of dependency zitadel/saml to provide all functionality for
handling of SAML requests and responses.
# Additional Context
Closes#6053
