Hi, We use AD to authenticate users for our Linux-servers. Recently we started to try out dnsmasq in order to get better dns-request performance, better resiliance (more dns-servers, avoid timeout:1, etc with the standard glibc resolver).
Today I noticed that about every fifth logon attempt is a lot slower than normal (10x the time). If I stop dnsmasq the slowdowns seems to dissapear. I can see with many ad-related dns-queries with wireshark when logon is slow like ForestDnsZones.mydomain and DomainDnsZones.mydomain. The replies are large (tcp-based) these queries returns 20-30 A-records for many domain-controllers. Are you aware of similar problems with the dnsmasq / ad-integration combination? Thanks, Erling
