Redirection by the CAS Headers

[talbenbasat]

Hi,

I've been using the mod_auth_cas, and tried to execute a redirect by user.
In order to do so, I'm trying to use the Apache RewriteRule with the cas headers.

I've been trying unsuccessfully to locate the exact headers name.

I would really appreciate if you could help me with,

Thanks in advance,
Tal

The standard "REMOTE_USER" will be set by mod_auth_cas after successful
validation.

Hi,

I've tried this rule
RewriteRule ^/$ http://webtest.domain.com/%{REMOTE_USER}

and it ended up with a redirection loop.

What is the URL that is first accessed? Is it webtest.domain.com/, or a
deeper path?

Is http always used, or is first access via https?

Can you post your CAS config?

Have you confirmed this works without the redirect, either by using
"require user foo" within your httpd.conf block, or with a CGI that prints
REMOTE_USER?

Note - you should probably take this to the cas-user mailing list for a
wider audience to help troubleshoot.

Hi @forsetti,

First of all, thanks for your quick responses.

1. The first URL i'm accessing is logintest.domain.com, and then it's redirects me to my apache.
   The physical architecture is Apache and haproxy for all subdomains on one server, and CAS with tomcat on another.
2. The URL - logintest.domain.com is accessed via https and all other URLs are access via http.
3. cas config

    #mod_cas_auth configuration
    CASCookiePath /cas/cookies/
    CASLoginURL https://logintest.domain.com:8443/cas/login
    CASValidateURL https://logintest.domain.com:8443/cas/samlValidate
    CASDebug On
    CASValidateServer Off
    CASAllowWildCardCert On
    CASTimeout 86400
    CasIdleTimeout 86400
    CASSSOEnabled On
    CASValidateSAML On
    CASCacheCleanInterval 1800
    CASAuthoritative On
    CASCookieDomain .domain.com

1. apache location directive

  <Location />
     AuthType CAS

     require valid-user

     CASAuthNHeader Cas-User

     CASScrubRequestHeaders On

     CASScope /

     CASCookie domain
  </Location>

Sorry for delay (I travel much for work lately). When accessing
webtest.domain.com, is https ever used? Or just http?

Have you verified that this will work without the redirect, by just
protecting a directory and making sure you can gain access?

I'd suggest [osting

As this is likely not a mod_auth_cas bug, I'd suggest posting this to the
cas-user mailing list for a broader community discussion.

Hi @forsetti,

Yes https is being used when entering logintest.domain.com.

I'll post the question in the cas-user mailing.

Thanks,
Tal
