SAML integration is not described anywhere as it is handled manually. Configuration must be done on both side - ASM and customer IdP. ASM can be integrated with any identity provider that supports SAML2.
Broadcom needs from the customer:
1) entity ID
2) SSO url
3) SLS url (optional)
4) the public certificate
5) list of emails they want to integrate (it can be changed later)
We provide (everything in one XML file and is usually called metadata):
7) our SLS
8) some configuration details (e.g. what format we support etc.)
Both we Broadcom and our customer need to configure their services to cooperate and to accept the SAML requests. On the customer side, they need someone who can configure their IdP and provide us with the 1)-5) items above.
