So I did a tad bit more research because I didn't want to configure Dovecot to use LDAP. I wanted to use pam because the dovecot pam module would continue to be used. It's just easier that way! Anyway, I noticed this option for the pam driver in passdb: cache_key=<key> I ended up adding this to the "args" list: cache_key=%u%n I also set these: auth_cache_size = 1024 auth_cache_ttl = 1 hour auth_cache_negative_ttl = 0 Now Roundcube is flying again, just like it was before I made Dovecot use FreeIPA. The slow auth issue is gone. Thanks for listening! -- Ranbir
