With the upgrade to LoadRunner Version 12.50, SAML is fully supported; however, this support extends ONLY to the Web Services protocol.
SAML Security Options:
VuGen supports SAML (Security Assertion Markup Language) for Web Services. SAML is an XML
standard for exchanging security-related information, called assertions, between business partners over
the Internet. The assertions can include attribute statements, authentication, decision statements, and
authorization decision statements.
