Opened: Feb 24, 2017

Severity: 3-Major

Symptoms

Accessing SAML Resource causes RST when Single Sign-On (SSO) on access profile contains V1 configuration (NTLM, form based).

Impact

TCP connection to the client is reset. As a result, APM end user is not able to perform IdP-initiated SAML WebSSO.

Conditions

All of the following: - BIG-IP system is configured and used as SAML Identity Provider. - In-use access profile has both: 1) V1 SSL attached (NTLM, form based) and SAML resources assigned on access policy. - APM end user performs IdP-initiated SAML WebSSO by clicking published SAML resource on the webtop.

Workaround

None.

Fix Information

Assigning V1 SSO profile on access policy no longer causes a connection reset when APM end user performs IdP-initiated SAML WebSSO by clicking published SAML resource on the webtop.
