Problem with certificate import

We have problem regarding import of a SSL certificate (.pfx).

For import of the certificate, we are using org.nuxeo.ecm.directory.api.DirectoryService and org.nuxeo.ecm.core.api.DocumentModel packages, further using:

certificate = session.createEntry(map);

where:

Map<string, object=""> map = new HashMap<string, object="">(); map.put("userid", userID); map.put("filename", userCertificate.getFilename());

ByteArrayOutputStream byteOS = new ByteArrayOutputStream(); String keystore64Encoded = Base64.encodeBytes(byteOS.toByteArray()); map.put("keystore", keystore64Encoded);

and session is an org.nuxeo.ecm.directory.Session and certificate is DocumentModel certificate.

The error we get in the log is the following:

org.nuxeo.ecm.directory.DirectoryException: createEntry failed

In case of trying to update an existing certificate, with newly generated we get the following error:

Exception during saving certificate.org.nuxeo.ecm.core.api.WrappedException: Exception: org.nuxeo.ecm.directory.DirectoryException. message: updateEntry failed for 'username'.

Can you please help us with some direction regarding this issue ?

Thank you very much in advance, A.
