Last_login plugin and mysql

[Thomas Hooge]

Hello,

i have problems configuring the last_login plugin with mysql.

I have extended the postfixadmin database with a new field,
configured the plugin as described in the wiki.

Finally i got errors: table is not writable, INSERT failed.

Why is the insert required? The plugin should only UPDATE
the column for existing rows.
Or am i missing some configuration options?
Here is my dictionary config:

map {
  pattern = shared/last-login/$user
  table = mailbox
  value_field = x_last_login
  value_type = uint

  fields {
    username = $user
  }
}


Dovecot: 2.2.27 (c0f36b0)

Kind regards,
Thomas
