SAML 2.0 Single Log Out (SLO) issue with iOS & PhoneGap

I am using Phonegap and jQuery AJAX calls to perform logout like below

$.ajax({ url: logoutURL, type: "POST", data: {}, cache: false, 
success: function(data, textStatus, jqXHR){........}, 
error: function(jqXHR, textStatus, errorThrown){  
     alert("Logout Failed.");  
     enableAllButtons(); } });          

the logout URL is a SAML 2.0 Single Log Out (SLO) URL. I have tested this on Android it is working perfectly fine. But when I tried the SLO on ios specifically iPad ios 6.1.3 it will fail and it returns me with a http 0.

I just found out from the IDP log that for android it has a warning of "Client Certificate error, IP address" but it will then automatically attempt to create outgoing SSL connection without trusted certificates. on the other hand, on iOS it does not continue the connection after the signed assertion was issued.

How can I get this solved or is there a way for me to bypass the cert problem?

All advice are appreciated.

    I found out that it is a problem with iOS SDK limitation on AJAX calls to HTTPS with self signed cert.

    This linked provided me the answer:

    All I've got to do is to write a piece of code in AppDelegate.m and the problem was solved.

    @implementation NSURLRequest(DataController)

    + (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host


    // ignore certificate errors only for this domain

    if ([host hasSuffix:@""])


    return YES;




    return NO;




    However, this is only advisable to be done on Development environment where the certs are not properly signed.

    Hope this helps some of you who are facing similar issues
