NetIQ eDirectory tends to be the other big one. Although I am seeing a rise in companies not having an SSO solution recently at all. In fact some of the SMEs I've seen recently are running most of their stuff entirely via basic Microsoft O365 accounts or iCloud.

A lot of startups or smaller companies I've worked with are entirely on the Google stack (gmail, google drive). I imagine there's a scale when that option breaks, but I think it'd be fine until 50-100 employees.

I've seen it working for schools with 5000+ account so it'll go well past 100 users. Not sure I'd want to depend on Google though.

That's great. I thought I heard of colleges where the entire campus was on the Google stack.

Looks like University of Arizona uses it: https://it.arizona.edu/google-storage which has 50k students: https://en.wikipedia.org/wiki/University_of_Arizona

No personal familiarity with it at that scale, though.

I wouldn't think SSO is the primary use for AD. Definitely one big use, though!

[connordoner]

What do you think the primary use is?

[roflyear]

User and resource management, I'd say.
