Hi,

Thanks to log messages from remoteuser.py in "./lib/galaxy/web/framework/middleware/remoteuser.py":

      print('affichage des variables d acces')

      print ('self domain : %s'%self.maildomain)

      print ('path info : %s'%path_info)

      print ('admin user : %s' %self.admin_users)

      http_remote_user = environ.get('HTTP_REMOTE_USER','')

      print ('http remote user : %s'%http_remote_user)

      remote_user = environ.get('REMOTE_USER', '')

      print ('remote user :%s' %remote_user)

Galaxy prints every environment variable it receives, and I have seen that HTTP_REMOTE_USER variable is "(null)".

Moreover, Galaxy is defined as a valid Proxy (reverse proxy ??) so galaxy.conf is :

<VirtualHost localhost:port> # Define Galaxy as a valid Proxy <Proxy localhost:port> Order deny,allow Allow from all

Hi Sarah,

Please recheck the syntax in the documentation:

http://wiki.g2.bx.psu.edu/Admin/Config/Apache%20Proxy

The following directives should be in the <Location> block, not the <Proxy> block.

--nate

     RewriteEngine on

# Take the $REMOTE_USER environment variable and set it as a header in the proxy request. RewriteCond %{IS_SUBREQ} ^false$ RewriteCond %{LA-U:REMOTE_USER} (.+) RewriteRule . - [E=RU:%1] # Set the REMOTE_USER header to the contents of the LDAP query response's "uid" attribute RequestHeader set REMOTE_USER %{AUTHENTICATE_uid}e

 </Proxy>

<Location "/....." > AuthType Basic AuthBasicProvider ldap AuthName "Galaxy" AuthLDAPURL "ldap://serveur ..." AuthzLDAPAuthoritative on Require valid-user

</Location>

</VirtualHost>

But, I didn't achieve, yet , to access REMOTE_USER value throught proxy.

In universe_wsgi.ini, *use_remote_user = True*

and *remote_user_maildomain = toulouse.inra.fr*

Thanks in advance, Sarah

Hi Brad, Hi Christopher,

Thanks a lot. I'm talking to Open LDAP. I have changed

RequestHeader set REMOTE_USER %{AUTHENTICATE_uid}e to RequestHeader set REMOTE_USER %{AUTHENTICATE_UID}e

But I always have the same message /(Access to Galaxy is denied Galaxy is configured to authenticate users via an external method (such as HTTP authentication in Apache), but a username was not provided by the upstream (proxy) server. This is generally due to a misconfiguration in the upstream server. )/

Hi Sarah,

This configuration will need to be in your Apache config (the location of which varies depending on your OS and/or how Apache is installed) rather than an .htaccess file.

--nate

This is my .conf file : <Proxy http://localhost:8080%3E Order deny,allow Allow from all </Proxy>

 RewriteEngine on

 <Location "/">
         AuthType Basic
         AuthName Galaxy
         AuthBasicProvider ldap
         AuthLDAPURL "ldap://server/ou=People,ou=genopole,ou=toulouse,o=inra,c=fr?u

Thanks in advance, Sarah

Hi Sarah:

I don't know what kind of LDAP you're talking to... I'm talking to Active Directory and this configuration works in that situation.

Order allow,deny allow from all

          AuthType Basic
          AuthName "NEB Credentials"
          AuthBasicProvider ldap
          AuthzLDAPAuthoritative off
          AuthLDAPBindDN ccalookup@neb.com
          AuthLDAPBindPassword <password>
          AuthLDAPURL

"ldap://<ldap.domain.com>:389/dc=domain,dc=com?sAMAccountName" require valid-user RewriteCond %{IS_SUBREQ} ^false$ RewriteCond %{LA-U:REMOTE_USER} (.+) RewriteRule . - [E=RU:%1] RequestHeader set REMOTE_USER %{AUTHENTICATE_sAMAccountName}e
