downloadWhy can't I download this file?When you configure SAML authentication,you create the following settings:

IdP Certificate Name. This is the public key that corresponds to the private key at the IdP.
Redirect URL. This is the URL of the authentication IdP. Users who are not authenticated are redirected to this URL.
User Field. You can use this field to extract the user name if the IdP sends the user name in a different format than theNameIdentifier tag of the Subject tag. This is an optional setting.
Signing Certificate Name. This is the private key of the NetScaler Gateway server that is used to sign the authentication request to the IdP. If you do not configure a certificate name, the assertion is sent unsigned or the authentication request is rejected.
SAML Issuer name. The name to be used in requests sent from NetScaler to an IdP to uniquely identify NetScaler.

Requirements
1. AAA Vservers.

2. Idp Signing Certificate: This certificate is use to sign the SAML assertion. This certificate is send to SAML Service Provider (SP)
3. SP Signing Certificate: This certificate is same as Idp certificate but the private key is on the SP and the NetScaler only holds the public key.

Bind the Server Certificate and Basic authentication policy.
Also bind the SAML Idp policy to IDP Vserver

Make sure you give SAML IDp policy priority low as compared to LDAP policy.
For example if SAML IDp policy priority is (90) so LDAP priority should be 100.

Configuration of AAA SP vserver

No need to bound LDAP policy here.
