Exception "Failed to convert the base-64 encoded string into XML"

SAML for ASP.NET
1

We have a form that takes a password as input, and then makes a SAML request. When we use that form from a regular desktop, it works as expected, but when we use the form from an iPAD, we get this exception:

ComponentSpace.SAML2.Exceptions.SAMLSerializationException: Failed to convert the base-64 encoded string into XML.
at ComponentSpace.SAML2.Utility.SAML.FromBase64String(String text)
at ComponentSpace.SAML2.Bindings.HTTPPostBinding.GetFormVariables(HttpRequest httpRequest, String messageFormVariableName, XmlElement& samlMessage, String& relayState)
at ComponentSpace.SAML2.Bindings.HTTPPostBinding.ReceiveRequest(HttpRequest httpRequest, XmlElement& samlMessage, String& relayState)

Any known issues with iOS and the SAML component?

We’re not aware of any issues related to iOS devices. Our testing includes Safari on an iPhone and iPad.

The attachment is of the SAML response XML rather than the encoded string.

Please enable SAML trace and send the generated log file as an email attachment to support@componentspace.com mentioning your forum post.
