.net - Any good Resources for WCF Delegation? -

-

i'm trying setup wcf delegation, without success (the scenario client > frontend server > backend server).

in theory, should straight forward using kerberos (i have windows domain), in practice i'm running weird errors things sspi or basic message security.

i found countless shallow resources, , forum posts people had problems , guessing solutions through trial , error. looked @ table of contents @ so-called "pro" , "expert" wcf books, delegation seems no 1 wants cover (in fact, there typo in 1 of exceptions .net throws makes me feel not microsoft bothers it).

anyway, there resource has clue , confidence explain whole process a-z, using methodological approach actual explanations , not meaningless code blocks don't work , never explained?

this more kerberos problem wcf problem.

the basic idea client makes request under security context frontend server, security context sent on backend server.

this cannot fixed in code. computer forwards kerberos token must trusted that. account code running under must trusted forward security token.

for general kerberos: http://support.microsoft.com/kb/907272

this kerberos sharepoint, there lot in common: http://blogs.msdn.com/b/martinkearn/archive/2007/04/23/configuring-kerberos-for-sharepoint-2007-part-1-base-configuration-for-sharepoint.aspx
