Issues to Configure SAML ,I tried alot but its not working ,Below Given instruction how to configure SAML

Question

SAML Overview
Security Assertion Markup Language (SAML) is an XML-based standard for exchanging authentication and
authorization data between security domains, that is, between an identity provider (a producer of assertions)
and a service provider (a consumer of assertions). SAML is a product of the OASIS Security Services
Technical Committee.
SAML is relevant to those customers who already have a SAML implementation in use with other systems in
their organization. Therefore, it is recommended you engage your technology team that has a working 
knowledge of SAML and provide this document to them for their review.
Key Roles
• Identity Provider (IDP): The system in authority that provides the user information
• Service Provider (SP): The system that trusts the asserting party’s information, and uses the data to
provide an application to the user.
• Subject: The user and their identity that is involved in the transaction.
Note! In our context, Learning Maestro is the SP, the IDP is customer-specific, and the Subject is the user
who is logged in.

Implementing SAML 2.0
• SumTotal LMS supports only SAML 2.0 Standards.
• We support only IDP-initiated SAML authentication.
• The SAML Response should be signed and base64 Encoded.
• UserName should be passed in NameID element under Assertion\Subject Keys.
• We use the timestamp provided in IssueInstant attribute of SAML Assertion to find the valid period
(+/- 5 min ) for the SAML Response.
• Currently, we do not support signed or encrypted assertions.
• Deep linked URLs can be passed through an additional URL parameter of “OriginalURL.”

When Learning Maestro is Accessed from a Portal
1. The user logs into the customer portal.
2. The user clicks on a link to the LMS from the customer’s portal.
3. The link points to an IDP page.
4. The IDP pages posts an HTTP Request to Learning Maestro
5. The request is an < ... > message.
Typical Structure of a SAML Response
• Below is the typical SAML Response received by LMS from IDP
• Value of SAMLResponse parameter should be base64 Encoded.

Configuring SAML 2.0
SumTotal Maestro supports SAML 2.0 for the “Identity Provider Initialized SSO” protocol.
To configure your Maestro domain to accept SAML 2.0 Assertions, the following steps must be taken:
1. Confirm that Usernames are in sync
2. Provide an X.509 Certificate to SumTotal Systems (SHA1 Hashed)
SumTotal Systems will configure your environment with the X.509 cert you provide.
3. Point your call to the following URL:
https://gm1.geolearning.com/geonext/<your_domain>/saml.geo
After authenticating to your Identity Provider, the provider will pass a user into Maestro IF:
• The user has a username matching an existing Maestro username
• The x509 certificates match on both sides
If authentication fails, the user will be presented with a failure page.
Assertions
An optional assertion is available to specify the URL a user will be sent if there is an authentication error.
ErrorRedirectURL Assertion
• If ‘ErrorRedirectURL’ is not specified and an authentication error or other security exception 
occurs it will redirect the user to the default secerror.geo page as it does today
• If a value (URL) is specified for ‘ErrorRedirectURL’ and there is an authentication error the user 
will be redirected to the URL specified

FAQs
Question Answer
What .NET library are we using? SumTotal uses “Componentspace” net SAML 2.0 library
Can users still log in via the login page? Yes. The SAML target page is different than the login page.
Can we deep link into the LMS through 
the SAML 2.0 authentication workflow?
Can I get rid of the Logout button?
What is the Session timeout setting? Session Hard Life and Idle Life settings can be configured in 
What is the unique ID for SAML? The “username” field.
Yes. “Deep Link Target” (target or original URL parameter) is 
accepted. If none is provided, then it will default to the default 
landing page as configured in Maestro.
Yes, When using SAML, the logout button still exists 
intentionally in the navigation but can be disabled in the 
“configure Navigation” options.
the security section of the administration interface of Maestro.
What is the failure page if
Authentication fails?
If the authentication fails, by default an intentionally simple error
is presented to the user stating “Authentication Failure”.
For security purposes, no further information regarding the 
specifics of the failure are defined to the user.
An optional ErrorRedirectURL assertion can be used.
What URL do we point to? https://gm1.geolearning.com/geonext/<your_domain>/saml.geo

Hello,
Thanks for posting your question to here. However, this forum is used to discuss and ask questions about .NET Framework Base Classes (BCL) such as Collections, I/O, Regigistry, Globalization, Reflection. For issues regarding configuring SAML, this is beyond
the scope of our support.
Regards.
We are trying to better understand customer views on social support experience, so your participation in this interview project would be greatly appreciated if you have time. Thanks for helping make community forums a great place.
