How To: Breaking up the HTTP Authorization Header

For breaking up the HTTP Authorization Header to create username and password attributes, you will need to use 3 tasks.

1. Identify Document (header filter)

Filter Type = Request Header 
Header Name = Authorization 
Comparator = map-to 
Value Type = Template 
Value = Basic {basic64}

2. Convert Value (attribute conversion)

Operation = Base64 Decode 
Attribute Type = User Attribute 
Attribute Name = basic64

3. Map Attributes and Headers (new mapping)

Source Type = User Attribute 
Source Name = basic64 
Target Type = Template 
Target Name = {username}:{password}

You will now have 2 user attributes "username" and "password" which can be used with the User Identity task for auth via attribute mapping.
