When BIG-IP is used as SAML SP, and SLO is not properly configured on associated saml-idp-connector objects, IdP initiated SAML SLO may result in memory leak in SSO plugin.
SSO plugin leaks memory
- BIG-IP is used as SP. - Associated saml-idp-connector object has 'single-logout-uri' property configured, but 'single-logout-response-uri' property is empty. - User performs IdP initiated SAML SLO
There are two possible workarounds: - Fix misconfiguration: Configure SLO correctly by adding value to 'single-logout-response-uri' property of IdP connector object. - Disable SLO by removing single-logout-uri' property of IdP connector object.
When fixed, memory will no longer leak in SSO plugin even when SLO is misconfigured.
