we would to publish our experience with privacyIdea 2.19
and postgres Bdr (Multimaster).
We have 3 vm node with privacyidea installed and 3 node with postgres multimaster (postgresql-bdr94-2ndquadrant) installed.
2 vm in Italy and 1 in other region in Europe (freeradius+privacyID3a).
2 vm in Italy and 1 in other region in Europe (Postgres 9.4 BDR)
All health check and load balance are checked by a Network LB (every minute).
Each FrontEnd of Privacyidea point directly to a single node of Postgres Multimaster.
We use this scenario for Prod Internal purposes and all works well for about a year.
I wanted to publish this experience to show how everything working very well.
