Windows AD and SSO

[Crisman]

Hi,

Besides the external contributor has not already put the plugin available, is there any way to implement the SSO/AD with the current firmware?

Regards,
Crisman.

The plugin is available, but not advertised as it is in development mode. You can install it from the console and it should then show up in the services menu:

# pkg install os-web-proxy-sso-devel


Cheers,
Franco

FYI: The plugin code is here:
https://github.com/opnsense/plugins/tree/master/www/web-proxy-sso

@fichtner: there is an really old ticket: https://github.com/opnsense/plugins/issues/43

Yes, but we don't want to release something that is not approved by the maintainer, even if we fix that list.

Sorry to ask again, but is there any solution to this error?

Error: ldap_sasl_interactive_bind_s failed (Unknown authentication method)\tadditional info: SASL(-4): no mechanism available: No worthy mechs found

OPNsense 17.1.10-amd64


I have tried in many ways to solve, even with older versions (16.7) and I can not make the plugin work.

I tested it with 17.7r1 and it says /usr/bin/kinit: not found.
That would be awesome if this becomes stable.

Hi Andy,

Thanks for this hint, the paths to kinit / kdestroy are definitely wrong, apply this patch[1] to fix that:

# opnsense-patch -c plugins 3189ebd1

I really don't know about the state of this, it somehow worked a while back, but we had several open issues and at least for me personally no test setup to be able to finish it.


Cheers,
Franco

Thank you Franco! But now joining domain dies with the following error:

Code Select Expand

Also the category in the menu-tree is not correct. It is listed under "Proxy" but the new category is "Web Proxy".

Thanks for your awesome work!

Hi Andy,

Thanks for the fix. The switch from Heimdal to MIT Kerberos seems to have taken its toll on the implementation. It looks like "-k -t file" should be used, if the file specified needs a different contents I do not know...
