Comment 2 for bug 1526558

A new working branch user/jeffdavis/lp1526558_sip_auth_proxy_rebased is available:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp1526558_sip_auth_proxy_rebased

This branch does two things:

- Rebases Galen's branch to current master.
- Uses native Evergreen auth for SIP client login by default, even if AuthProxy is enabled. The client credentials will commonly be known only to EG, so we should avoid spamming the central authentication system with auth requests that are bound to fail (especially since some SIP clients do a fresh login every 5 minutes or so). Those who do want client login to go through the authentication proxy can add the following to the <options> block in SIP implementation_config:

<option name='use_proxy_for_client_login' value='true' />
