Instructions copied from MDL-76929.

Verify lib version

1. Access to "Site administration / Development / Third party libraries".
2. Verify third-party lib versions for PhpXmlRpc is 4.11.0

Testing scenario

The goal of this test is to ensure that it is possible for Moodle users to connect with another Moodle site using MNet.

Setup

Please note: it's possible that you see some notices during the setup part depending of the debugging levels in your site. You can ignore them as far as the configuration works as expected.

1. Setup a couple of Moodle sites:
   • site1 running older version, for example: Moodle 4.3.x (MOODLE_403_STABLE).
   • site2 running the version to be released (master).
2. In the file /etc/ssl/openssl.cnf search for the section openssl_init and make the following changes, so this part of the file looks like the following:

   [openssl_init]

   providers = provider_sect

   [provider_sect]

   default = default_sect

   legacy = legacy_sect

   [default_sect]

   activate = 1

   [legacy_sect]

   activate = 1

3. Run the following command and verify it does not throw an error:

   echo -ne "test" | openssl rc4-40 -K 7465737473 -nosalt -e -nopad | xxd

4. Make sure you have basic network connectivity between the two sites.  eg. you can curl/wget the URL for site1 from site2 and vice versa
5. Make sure that the IP and port of both sites are not blocked. Navigate to: Administration > Security > HTTP security and make sure the site IP and ports are not in "cURL blocked hosts list " and "cURL allowed ports list ". (you can just clear both lists)
6. Ensure that they have different $CFG->sessioncookiepath settings either on config.php or in Administration > Server > Session handling
7. In both sites, enable and configure MNet as explained in the doc page.
8. - Please note: You don't need to configure the "remote enrolments" steps, only the "get users roaming" ones.
9. Create user1 in site1 and user2 in site2.

Testing

1. Log in as user1 in site1 and go to "Site home".
2. In the "Network servers" block (that has been added as per the configuration instructions, click on site2.
3. Verify that now you are welcome to site2 as user1.
4. Log in as user2 in site2 and go to "Site home".
5. In the "Network servers" block (that has been added as per the configuration instructions, click on site1.
6. Verify that now you are welcome to site1 as user2.
7. Verify that now user1 and user2 do exist in both sites and SSO/roaming between them works as expected.

Code verified against automated checks.
