Moodle: 3.0
Host: MoodleRooms
Active Directory: Windows Server 2012 R2
To preface this: Our LDAP Authentication has been working, the issue isn't the authentication itself. I'm trying to run the LDAP Synchronization and move our LMS towards SSO.
I ran LDAP Synchronization first three evenings in a row. Times to complete were approximately 5 hours, 5 hours, and then 9 hours. We currently have about 17,000 accounts. So a lot, but run times of that seem extreme. When I went to research this, I couldn't find much information about speeding it up. I increased the Extra PHP memory limit under Site Admin > Server > Performance to 4gb.
I also saw one person say that putting an index on the mdl_users table on the username field would assist speeding it up, but because we're on MoodleRooms I can't do that.
Any help/pointers on what to look into would be appreciated.
