1.6.1626159071 (13-Jul-2021)

  • CryptoProCli for installed certificates testing added

  • Minor fix for updating MDLP message processing status

  • Due to an issue in API 5.17 for the old (> 30 days) doctype 200 (ticket), API 5.19 additionally applies.

1.6.1622484348 (31-May-2021)

  • fix for MDLP issue: webdav link is ready, webdav document is empty, HTTP response 200. In the case of an empty document on webdav, the behavior of the connector is the same as for 1.6.1620820199.

1.6.1620820199 (12-May-2021)

  • fix for MDLP issue: webdav link is ready, webdav document not found, HTTP response 404.
    The connector will retry loading from webdav until "dead_lock_delay" before reporting "NO_DOCUMENT_IN_MDLP" to ATTP.
    New logic applied: document_create_date + dead_lock_delay < now () && "404 from WebDAV" then return "NO_DOCUMENT_IN_MDLP"
    New parameter: dead_lock_delay in mdlp-connector.json // in seconds, default 10800 = 3h

"update_document_status": {
      "dead_lock_delay": 3600,

  • OMS dynamic token request support added (without TTL based storing on Java side)
