Nginx module to use SPNEGO+GSSAPI+Kerberos for HTTP authentication ================================================================== Testing ------- Authentication has been tested with (at least) the following: Software Nginx 1.2.3 Internet Explorer 8.0.7600.16385 Firefox 10.0.6 Chrome 20.0.1132.57 Curl 7.19.5 (GSS-Negotiate), 7.27.0 (SPNEGO/fbopenssl) The underlying kerberos library used for these tests was MIT KRB5 1.7 History ------- Michael Shadle paid YoctoPetaBorg from RentACoder to develop this extension as ngx_http_auth_sso_module. Michael then renamed it to ngx_http_auth_spnego_module. This initial module provided spnego support using Microsoft's sample spnegohelp files. Since then, SPNEGO support has made its way into various GSS/Kerberos libraries. Various other people have contributed minor patches to make the extension work in their environments. Provenance ---------- The initial codebase was a fork of Apache's mod_auth_gss_krb5 0.0.5 (http://modgssapache.sf.net) with changes to support nginx. Compilation ----------- When compiling from source build as usual adding the --add-module option: ./configure --add-module=$PATH_TO_MODULE inside top Nginx source directory. Configuration ------------- The module has following directives: - auth_gss: "on"/"off", for ease of unsecuring while leaving other options in the config file, - auth_gss_realm: what Kerberos realm name to use, for now only used to remove it from full [email protected], - auth_gss_keytab: absolute path-name to keytab file containing service credentials, - auth_gss_service_name: what service name to use when acquiring credentials. (TOFIX: HTTP but should be a list in case of some other browsers wanting perhaps khttp or http) TOFIX: for now they are all merely location specific. i.e. no way to specify main or per server defaults, except for ... Examples -------- ... current "hardcodeds" ;-} location /topsecret { auth_gss on; auth_gss_realm LOCALDOMAIN; auth_gss_keytab /etc/krb5.keytab; auth_gss_service_name HTTP; } Additional Information ---------------------- Generating a keytab with an HTTP SPN will be specific to your environment. As with many things, ask your local administrators or try examples on Google until you find something that works.
