So, I have CasOwa (https://wiki.jasig.org/display/CAS/CASifying+Outlook+Web+Access+2010) CAS 3.5.1 working with Exchange 2010. I seem to be getting Proxy failure error with re-login.
Normal operation works fine, Browse to http(s)://webmail.exchange.edu/casOwa redirect to CAS for auth and then get redirected to https://webmail.exchange.edu/owa. The problem arises if a user tries to browse to https://webmail.exchange.edu/casOwa in a second tab (however http://webmail.exchange.edu/casOwa works fine). The browser displays a DTD is prohibited in this XML error, the casowa log states that my cas clearpass url is unauthorized. Looks like this line string proxyTicket = CasAuthentication.GetProxyTicketIdFor(ClearPassUrl); in CasOwaAuthHandler.cs is returning a blank value. ERROR in Browser Server Error in '/casOwa' Application. For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method. ERROR in casowa log NetCasClient.HttpModule Verbose: 3237 : Starting AuthenticateRequest for /casOwa DateTime=2013-06-12T20:51:01.6334286Z DotNetCasClient.HttpModule Verbose: 3237 : Ending AuthenticateRequest for /casOwa DateTime=2013-06-12T20:51:01.6334286Z DotNetCasClient.Protocol Information: 3237 : Proxy failure: The supplied service 'https://cas.server.edu/cas/clearPass' is not authorized to use CAS (UNAUTHORIZED_SERVICE) DateTime=2013-06-12T20:51:01.6490289Z DotNetCasClient.HttpModule Verbose: 3237 : Starting EndRequest for /casOwa DateTime=2013-06-12T20:51:01.6646292Z DotNetCasClient.HttpModule Verbose: 3237 : Ending EndRequest for /casOwa Any suggestions on how I should proceed? Let me know if you need additional information.
