Subject: Move code that connects to ILS back end out of
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=a0140fe512a9a5f68af200cf17042d275b9ff4aa;p=SIPServer.git

Move code that connects to ILS back end out of
sip_protocol_loop() and into handle_login().  This way, if
there's a problem loading or initializing the ILS implementation,
the client will be told that login failed, rather than
"successfully" logging in and then having the server die later.
