You're quite wrong here. Google, AT&T and Verizon on your list use OpenLDAP. OpenLDAP scales to billions of users in a single instance, and of course it distributes across multiple nodes for even greater scaling as needed. Most of the telcos around the world use it now; it scales far beyond every other data storage technology out there.

80% of the US population that owns cellphones are OpenLDAP users, whether they realize it or not. 90% of the US population that subscribes to cable TV (Comcast, Time-Warner, etc.) as well. Nothing else actually works for hundreds of millions of users. These companies know, they've tried a lot of "solutions" already.
- beagle3 12y agoThen I'm glad to stand corrected - I suppose I'm horribly out of date from the days they tried other "solutions". I'm less surprised about AT&T and Verizon, more surprised about Google. My own personal experience with LDAP in general (and some with OpenLDAP in particular) dates back to 2000 or so -- and at some point I just gave up on the complex and unreliable beast that it was (for whatever reason, BDB would occasionally lock up or get corrupted) - but I know a lot has changed since, LMDB is amazing -- I guess it is time for another look.
- hyc_symas 12y agoOpenLDAP didn't start to become seriously usable until about 2003 (that's when HP dropped SunDS and adopted OpenLDAP for all of their global infrastructure). A lot of work went into it in the 2001-2002 timeframe to get it there. Yeah, a lot has changed, you've missed a couple generations of advancements. BDB's complexity was definitely a pain, but that's all in the past.
