That's what I did! (prefixed with userdb_, since I'm using driver = prefetch)

passdb {
  driver = imap
    # Change the line below to reflect the IP address of your Exchange Server.
  args = host=exchange-imap.charite.de port=993 ssl=imaps
  default_fields = userdb_imapc_user=%u userdb_imapc_password=%w userdb_imapc_host=exchange-imap.charite.de userdb_imapc_ssl=imaps userdb_imapc_port=993
}

userdb {
  driver = prefetch
}
