You are allowed to do SASL authentication if <mechanisms 
xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/> has been advertized by the 
server.

After SASL authentication has been done, the stream gets reestablished 
by sending a stream header and new stream features.

All servers I know will not include the above stream feature again if 
authentication has already been done. Therefore with current 
implementations you are not able to do multiple SASL-negotiations on the 
same connection.
