You can configure Security Assertion Markup Language (SAML) authentication for Informatica web applications.
Security Assertion Markup Language is an XML-based data format for exchanging authentication information between a service provider and an identity provider. In an Informatica domain, the Informatica web application is the service provider. Microsoft Active Directory Federation Services (AD FS) 2.0 is the identity provider, which authenticates web application users with your organization's LDAP or Active Directory identity store.
SAML authentication cannot be used in an Informatica domain configured to use Kerberos authentication.
