Start LDAP Server $ docker run --rm --env LDAP_USERS=user01 --env LDAP_PASSWORDS=user01 -p 1389 : 1389 bitnami/openldap Configure Moodle Log in as admin Navigate to Plugins > Authentication > Manage authentication in site administration Ensure Prevent account creation when authenticating is not enabled Enable LDAP server Press Settings to configure LDAP server Set the following values: Host URL: ldap://localhost:1389 (or the IP address of the Docker container if not localhost) Distinguished name: cn=admin,dc=example,dc=org Password (Password for bind-user): adminpassword Contexts: ou=users,dc=example,dc=org Save changes Use Test settings from the Manage authentication page to confirm connection succeeds Test 1 In LDAP auth settings (in Moodle) specify to match those fields to fields in your LDAP. Notes: For the standard profile fields, make sure to map at least the firstname, lastname and email. You can use following mapping for this test: Data mapping (First name) -> cn, Data mapping (Surname) -> sn, Data mapping (Email address) -> mail Make sure that for each of these mapped fields, "Update local" is set to "On every login". Create some users in LDAP with data in those fields (inside LDAP container). Create a ldif file to create a user such as useradd.ldif: # Add John Smith to the organization dn: uid=jsmith,ou=users,dc=example,dc=org changetype: add objectClass: inetOrgPerson cn: JohnSmith sn: Smith uid: jsmith mail: jsmith @example .com Run `ldapadd -x -H ldap://localhost:1389 -D "cn=admin,dc=example,dc=org" -w adminpassword -f useradd.ldif` on the ldap server Run `ldappasswd -H ldap://localhost:1389 -x -D "cn=admin,dc=example,dc=org" -W -S "uid=jsmith,ou=users,dc=example,dc=org"` You will be prompted for password - type it, confirm (make sure to remember it - you will need it for login with LDAP users). Use adminpassword when prompted for LDAP password Repeat above steps to have multiples users (make sure changing uid, email, cn, sn) Run LDAP sync: `php admin/tool/task/cli/schedule_task.php --execute=\\auth_ldap\\task sync_task` Confirm users are created in Moodle and profile fields are filled. Change a user's field value in LDAP by creating a usermodify.ldif file e.g.: # Change John Smith to the organization dn: uid=jsmith,ou=users,dc=example,dc=org changetype: modify replace: mail mail: jsmith1234 @example .com Run `ldapmodify -x -H ldap://localhost:1389 -D "cn=admin,dc=example,dc=org" -w adminpassword -f usermodify.ldif` on the ldap server Repeat for other users as well Modify auth/ldap/auth.php and add sleep(30); after line 880 so it looks like this: $ this ->sync_roles($user); sleep( 15 ); Run the LDAP sync again: `php admin/tool/task/cli/schedule_task.php --execute=\\auth_ldap\\task sync_task` When seeing output like Updating user johnsmith3 id 127 Try to login as that user to Moodle Ensure you can't login - browser will keep loading Once next user started to process, i.e. when you see next record Updating user johnsmith4 id 127 Make sure you can login as user johnsmith3 Confirm users are updated in Moodle and profile fields reflect new value.
