THANK YOU VERY MUCH.

Do I use the extended metadata file at all or just the non-extended file
please?

I do not know about LDAP so I will see about adding something like this
to the bottom of the map file.  Some research showed the need for
AttritributeDecoder.  Did you have to do anything with that please?

The admin for the IDP sent me a screenshot of NamdID Format Current
Values.  Do you know if I have to do anything with this?  I hate GUIs.

 

urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

urn:oasis:names:tc:SAML:2.0:nameid-format:transient

urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified 

urn:oasis:names:tc:SAML:1.0:nameid-format:unspecified

Again, thank you.  This has been helpful.
