take a look at this snipped from your error code:
Authorization failed: OPTIONS of 'https://<redacted>:2443/svn/LS/branches/PRODUCTION-SUPPORT-1/ls-policygen': authorization failed: Could not authenticate to server: ignored NTLM challenge, rejected Basic challenge (https://<redacted>:2443) at /usr/local/libexec/git-core/git-svn line 943
specially at this part: Could not authenticate to server: ignored NTLM challenge
It looks like your company also changed autentication methods too.
Take a look at: Does git clone work through NTLM proxies?
I would take this steps:
- connect to your repository within your browser
- try to connect with another user account – probably you have some cache files in your home directory
- configure git or even svn according to NTLM auth
Good Luck,
