Crowd isn't supported in a clustered environment (
), but it can work in some configurations. CWD-1053
After configuring Crowd in a Tomcat cluster (Clustering/Session Replication HOW-TO) and pointing all instances at a common database, this is a tracking bug for the remaining issues.
- Crowd's web.xml does not mark it as <distributable/>
- Hibernate's second-level and query caches are enabled, so administration changes to settings are not communicated between instances
- Password reset tokens are not distributed; a password can only be reset against same instance that sent the email
- Synchronisation is not aware of clustering; any cached directories will fail when synchronisation runs at the same time
