mod_auth_gssapi additional NTLM auth request from Chrome
Last modified: 2016-03-22 10:11:19 EDT
This bug is created as a clone of upstream ticket:
Users are reporting a browser login popup in Windows Chrome (and IE?) browsers when attempting to log in to the IPA web UI.
According to Simo this is Chrome attempting to do NTLM auth by prompting the user for credentials.
An option is being worked on in upstream mod_auth_gssapi to not send additional WWW-Authenticate: negotiate requests: https://github.com/modauthgssapi/mod_auth_gssapi/pull/65
The pull request has more gory details on what is happening and why this wasn't seen in mod_auth_kerb.
Moving to mod_auth_gssapi given that the plugin first needs to gain support for it.
Not that the upstream feature only prevents a second request if negotiate fails.
But it will not prevent sending the initial negotiate option.
So I am not sure that Chrome behavior will see any change in this case.
People should probably configure chrome to not do ntlm auth by default, it is a security issue anyway to allow default ntlm auth to random websites.
