Authentication Error - XMPPFramework - Not Authorized

Question

After a successful connection to the server, i.e. after a successful callback to

- (void) xmppStreamDidConnect:(XMPPStream *)sender

Sometimes I get an authentication error, i.e. the following callback is called:

• (void) xmppStream: (XMPPStream *) sender didNotAuthenticate: (NSXMLElement *) error

NSXMLElement as follows:

<failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><not-authorized/><text>The response provided by the client doesn't match the one we calculated.</text></failure>

As I said, I get this from time to time. I traced this issue, and so far I have tried several things. Things I learned, and I can confirm so far:

• Username and password are 100% correct.
• I use SCRAM-SHA-1 authentication mechanism ( XMPPSCRAMSHA1Authentication )
• My server also supports the PLAIN mechanism, and it also does not work ( XMPPPlainAuthentication )
• If I try to disconnect when I get this error ( [xmppStream disconnect] ) and then in the xmppStreamDidDisconnect I try to reopen the stream ( [xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error] ), then I get into an infinite loop because the check authenticity ends sequentially

Now I have studied this even more, and using the SCRAM-SHA-1 mechanism, it looks like it is failing in the second call. The client sends something (seemingly valid) to the server, but it does not like the server and gives an not-authorized error.

Anyone's thoughts?

You must verify your username and password. If you use the wrong username and password for authentication / login, this didNotAuthenticate method will be called
