Installed new LDAP server just two weeks ago. Still allow manual authen for a handful of "special" user accounts. Using Moodle 2.5.
First upload of students to LDAP seems to work fine. However,subsequent uploads of existing students to other courses causes the auth method to change to manual.
Our process is:
1. Upload minimal info to LDAP server. It takes 2 hours to synch with moodle. (our LDAP was "built around" an existing system, not moodle)
2. Then we upload to a cohort and move the cohort into the first course.
3. A few weeks later, we use csv upload to add the cohorts and groups into other courses, as needed. Upon this second upload, the auth changes itself from ldap to manual. (then I have to do another upload to set it back) Is this expected behavior? The only way I can avoid this is by making sure the upload file (csv) contains a field for auth, set to ldap. Have not seen a discussion of this in the forums, so I'm wondering if some LDAP setting is wrong for us.
I'm including here a sample of all three upload files. Thanks to everyone who might weigh in on this....Kathleen
