[Dovecot] dovecot auth(default): Master request xxxx.xxxx not found

[Eric Sammons]

Hi,

Wondering if anyone could give some indication as to where to look for the
cause of the following error messages.  These error messages seem to occur
at about the time when users are having problems logging in.

Jun  8 10:33:19 host dovecot: auth(default): Master request xxxx.xxxx not
found

Using ldap for authentication and auth_cache is enabled, not sure if that
matters.

Thank you!
