i unable find supporting doco or web ref point me in right direction.

all appreciated.

fyi - might encounter issue, path case sensitive. key line is:

https://<server>/saml/' outside of application path '/saml'. 

i had web site in capitals link used in lower case:

<add value="https://<server>/saml/" /> 

matched case , solved problem.
