Hello,

It updates automatically on password mismatch. It's quite clear described here: https://wiki.dovecot.org/Authentication/Caching

What's not described is if the cache could survive restart... :-(

If users change their password how does the cache continue to work? Thanks 

Hello,

It's Submission only. It authenticates users with ldap, but I want to make sure it will work also on ldap connection failure. (And it works - auth cache does its job until Dovecot restart.)

Is it not in LDA?

Hello,

As far as I understand - auth cache it stored in memory, isn't it? Is
there a way for it to survive Dovecot restart?
