CILogon is the preferred authentication method for Globus Connect Server. For this method to work, your environment must meet two requirements:
All users have some form of active SUNetID. Full-service, sponsored, and base-level SUNetIDs are all allowed.
Users must use their SUNetID as their local username.
Here is how CILogon authentication works:
The end user chooses to use your Globus Connect Server endpoint.
Globus redirects the user to CILogon, which redirects the user to the normal Stanford login page.
Once the user authenticates, Stanford reports successful authentication to CILogon, who issues a time-limited certificate and private key to Globus.
CILogon is preferred because it uses the normal Stanford web login process, which means the user’s SUNetID and password do not go to any non-Stanford sites.
When Globus communicates with your endpoint, it uses the client cert issued by CILogon, which contains the end user’s SUNetID. That is how your endpoint knows who is using Globus.
To use CILogon authentication, you will be making additions to the
globus-connect-server.conf file that you first filled in during initial
Perform initial configuration first
If you have not already completed the initial configuration, do that first, and then come back here.
Here is the content which needs to be added to the
The one section will now be discussed in detail. If you do not need this explanation, you can skip ahead.
Security section is very simple:
[Security] FetchCredentialFromRelay = True IdentityMethod = CILogon CILogonIdentityProvider = Stanford University
globus-connect-server-setup that we will be using
CILogon, and CILogonIdentityProvider confirms that our users will be using
Stanford University credentials. The explanation for
FetchCredentialFromRelay is a little more complicated.
TLS is used to secure the communications between Globus and your endpoint.
With TLS, the server side must have a private key and certificate (if you run a
web site, you are probably aware of this already). Since Globus is initiating
connections to your endpoint, your endpoint needs a private key and
certificate. The FetchCredentialsFromRelay setting tells
globus-connect-server-setup to fetch a key and certificate from Globus, which
will be used for all future connections from Globus.
globus-connect-server.conf has been completed, it is now time to run
You should now run the
globus-connect-server-setup command. When you run
this command, you will be asked for your Globus ID’s password. Once that is
provided, setup will commence.
'sslv3 alert handshake failure' is OK
If you are running globus-connect-server-setup on a system running Python 3.1 or older, you may get the message 'sslv3 alert handshake failure'. This may be safely ignored. It is happening because your older Python is missing support for TLS SNI, which is required by downloads.globus.org (the Globus package repository). This issue has been reported to Globus.
Repeatedly prompted for ID and password?
If you are being repeatedly prompted for your Globus ID and password, that normally means that one of the two are incorrect. Remember, when prompted for your Globus ID, only enter the part before the at-sign.
Here is an example of the output from a successful run of
Password: Using MyProxy server on None Configured GridFTP server to run on sci-nfs-1.stanford.edu Server DN: /C=US/O=Globus Consortium/OU=Globus Connect Service/CN=cff864ae-3965-11e8-b98d-0ac6873fc732 Using Authentication Method CILogon Configured Endpoint quake-sci-nfs-1
globus-connect-server-setup is performing these steps:
Checking for newer versions of Globus Connect Server.
globus-gridftp-serverservice, and performing basic configuration.
Installing CILogon’s Certificate Authority, which GridFTP will use to verify client certs.
Requesting a server certificate and private key from Globus, which MyProxy and GridFTP will use when accepting connections from Globus.
If configuration was successful, the “Configured endpoint” message will be printed. At this point, services have been started and are ready for use!
Write down your Server DN
The Server DN is needed later in the configuration process, so make a note of it, until configuration is complete.
Now that Globus Connect Server (or, more specifically, MyProxy and GridFTP) is (are) up and running, you should finish configuration.
