LDAP Authentication

Postby bauler » Tue Nov 24, 2009 4:50 pm

Hi all,

i´m curious if there will be LDAP or any other kind of external authentication
mechanism in the near future. If yes, when?
Thank you in advance

I would like to support this request to. And I guess we have a half promise in

The native apache login system could be used and I think only relatively few changes would be required to the application. If the PHP equivalent of the CGI variable REMOTE_USER/AUTH_USER id used in place of the login page - then suddenly a lot different sources for authentication would be supported.

Yeah, I agree getting basic HTTP authentication in place is a good idea. Then Apache will handle the authentication with whatever modules it has available, including cool stuff like single sign-on Kerberos, etc. Reinventing this in web applications is usually a bad idea (and is easy to do poorly and/or in an inflexible way).

But! I would say it's more interesting to get granular LDAP authorization in place, meaning control over who can access what in the web interface. This would typically be implemented in the application itself, i.e. it will trust the web server's authentication, and then use the information the web server provides it (pretty much only the username in the case of Apache's mod_authnz_ldap) to query additional information (typically group membership) from an LDAP server, and then determine what the user is allowed to access.

When implementing this, it's essential that the configuration is flexible enough to allow any sort of group lookup (not only of type posixGroup, for example, but also groupOfNames, OU, etc) so that admins are free to adapt it to their LDAP-based system, be it OpenLDAP, Active Directory, eDirectory, or anything else.

The application would typically maintain the mappings of which LDAP group has access to which resource. The granularity of this is up to the implementor, but the basic approach would for example be to do something like Graylog2, where you have grant access to "streams". Streams are saved searches that can include anything like hostnames, regexes, etc.

If this is implemented, it's a good idea to check out SAML authentication and authorization for single sign-on as well. The SimpleSAML implementation does actually expose group membership to the web application, so implementing support for it would be trivial.

can someone please provide the steps to integrating authentication to web interface for log analyzer, and in my current environment we don't have LDAP setup, we use local credentials[/etc/passwd file] to login to box - is their simple steps that update configuration and integrate authentication.

or if HTTP authentication is simple and a good idea, can someone please provide the procedure.

and the current version I installed is 3.0.0 of log analyzer,

I am currently adding the LDAP implementation to the main Loganalyzer code. So if you wait for the next beta release of Loganalyzer, you will have LDAP support ready for testing.

lorbach, Thanks for your reply.

I think I may have confused you,

I my environment we don't have LDAP setup,

we use local files[/etc/passwd] to login to host, is their a way to integrate login credentials using local files on the server or if HTTP authentication is simple and a good idea, can you please provide the steps.

Thanks again,
