      Unit tests cover several aspects of this change, including ensuring that the new normalisation (in master only) spits out the expected results.

      In addition to this, you'll need to configure both auth_ldap and enrol_ldap and run some tests.

      Configuring your own LDAP server

      I've provided instructions for both Active Directory, and OpenLDAP

      Active Infectory
      1. Create some new Organisational Units (OU/containers) under moodle.test.com:

        -> moodle.test.com
        --> Builtin
        --> Computers
        --> Domain Controllers
        --> Foreign Security Principals
        --> Users
        --> Service    <-- ********
        --> Accounts   <-- ********
        --> Groups     <-- ********
        ---> 2016      <-- ********
        ----> Students <-- ********
        ----> Teachers <-- ********
        

      2. Under 'Service' create a new 'moodle' account. Give it a password which does not expire and cannot be changed. Uncheck the force password reset flag.
      3. Under 'Accounts' create a number of new accounts. Give them a password which does not expire but can be changed. Uncheck the force password reset flag.
      4. Set an e-mail address for all of the users
      5. Under 'Groups/2016/Students' create some new Groups:
        1. 2016-ECON101 (pre-Windows 2000 name = 2016-STUD-ECON101)
        2. 2016-MATH101 (pre-Windows 2000 name = 2016-STUD-MATH101)
      6. Under 'Groups/2016/Teachers' create some new Groups:
        1. 2016-ECON101 (pre-Windows 2000 name = 2016-TEAC-ECON101)
        2. 2016-MATH101 (pre-Windows 2000 name = 2016-TEAC-MATH101)
      7. Place several users in each of the subject groups (ECON101/MATH101)
      OpenLDAP
      1. Set up OpenLDAP as per https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-a-basic-ldap-server-on-an-ubuntu-12-04-vps
      2. Create a structure as follows:

        -> dc=yourhost,dc=per,dc=in,dc=moodle,dc=com
        --> ou=service    <-- ********
        --> ou=accounts   <-- ********
        --> ou=groups     <-- ********
        ---> ou=2016      <-- ********
        ----> ou=students <-- ********
        ----> ou=teachers <-- ********
        

      3. Under 'service' create a new 'moodle' account. Give it a password which does not expire and cannot be changed. Uncheck the force password reset flag.
      4. Under 'accounts' create a number of new accounts. Give them a password which does not expire but can be changed. Uncheck the force password reset flag.
      5. Set an e-mail address for all of the users
      6. Under 'groups/2016/students' create some new Groups:
        1. 2016-ECON101
        2. 2016-MATH101
      7. Under 'groups/2016/teachers' create some new Groups:
        1. 2016-ECON101
        2. 2016-MATH101
      8. Under each of the groups (ECON101/MATH101) add members using their dn, e.g.

        cn=springer,ou=Accounts,dc=auth,dc=banana,dc=per,dc=in,dc=moodle,dc=com
        

      Moodle setup

      Various things differ between AD and LDAP. Here are a few:

      1. bindDN:
        1. AD: moodle@moodle.test.com
        2. LDAP: cn=moodle,ou=Service,dc=auth,dc=banana,dc=per,dc=in,dc=moodle,dc=com
      2. Encoding:
        1. AD: cp1252
        2. LDAP: utf-8

        1. AD: MS ActiveDirectory
        2. LDAP: posixAccount
      4. ID Number Attribute

          2. Password: (the password you set)
        3. User lookup settings:
          1. User type: MS ActiveDirectory or `posixAccount`
          2. Contexts: ou=accounts,dc=moodle,dc=test,dc=com
          3. Search subcontexts: Yes
        4. User attribute: sAMAccountName

          3. Encoding: cp1252
        2. Bind settings:
          1. Distinguished name: moodle@moodle.test.com
          2. Password: (the password you set)

          1. Teacher:
            1. Context: OU=Teachers,OU=2016,OU=Groups,DC=moodle,DC=test,DC=com
            2. attribute: member

            1. Context: OU=Student,OU=2016,OU=Groups,DC=moodle,DC=test,DC=com
            2. attribute: member
          3. Member attribute uses dn: Yes
          4. User type: MS ActiveDirectory or `posixAccount`
          5. Id number attribute: sAMAccountName
        4. Course enrolment settings

          5. Summary: cn
        5. Autmatic course creation settings
          1. Auto create: Yes

      Using Andrew's AD server

      1. Run the attached config script (mdl51723.php)
      2. run an auth sync:

        php admin/tool/task/cli/schedule_task.php  --execute="\auth_ldap\task\sync_task"
        

        1. Check for errors
      3. run it again as the logic changes between creating and update users
        1. Check for errors
      4. Run the ldap CLI sync too:

        php enrol/ldap/cli/sync.php
        

        1. Check for errors
      5. Rerun
        1. Check for errors
      6. Open up your DB, find the users who were created, grab their IDs an enter them into a search such as:

        SELECT * FROM mdl_role_assignments WHERE userid IN (<list of ids here>);
        

      7. Make a note of the results
      8. Log into your site using the following credentials:
        username: springer
        password: Password1!
      9. Attempt to access one of the courses MATH101, ECON101
      10. Rerun your DB query
        1. Confirm that the results have not changed
      11. Edit settings for enrol_ldap and change

        nested_groups = false
        user_type = Default
        

        #Â Re-run the CLI sync

      12. Re-run the SQL query and note the results
      13. Login again as our Jerry Springer again
      14. Re-run the SQL query
        1. no change in result count

    • 3.1 Sprint 4

      LDAP auth and sync worked perfectly in 2.8.6+, now users are unenrolled when they login on 2.9.2+. No changes to the config from 2.8.6+ to 2.9.2+.
