ASSP supports having at least 1 backup LDAP server in it's config, not sure if it allows more than one but if as you say everything else is redundant you can change the ASSP config so that no 2 ASSP instances reference the same set of servers if you have at least 3 LDAP servers. As for the MySQL single point of failure...I completely agree. Thats always a problem with ANY database backed however. The only real solution is clustered servers sharing the same FQDN and some physical site-to-site replication. I suppose you could also create a script that polls LDAP and/or MySQL servers(in a Master Master replication) and if they are down stops ASSP changes the IP/name in the ASSP.cfg and then starts ASSP up again pointed at the new host. Thats just me thinking out-loud though. Feel free to point out holes in my ideas :) Kevin ------------------------------------------------------------------------- Take Surveys. Earn Cash.
