Description tocam74 2007-04-11 09:18:16 UTC
I'm using Entrust digital certificates, whose DNs have multiple CNs. For 
example Root CA certificate has DN like this: CN = TEST CA ROOT, CN = AIA, CN = 
Public Key Services, CN = Services, CN = Configuration, DC = catest, DC = ptt, 
DC = yu. All certificates are valid, and OpenOffice considers them valid, too. 
In OpenOffice 2.0 it was possible to sign documents without problems, but in 
OpenOffice 2.2 I can't sign documents with such certificate (when I select 
certificate and click OK nothing happens, and when i double-click certificate 
it appears that invalid signature was made, but it is never saved). But, I can 
successfully sign documents in OpenOffice 2.2 with certificate issued by 
Microsoft CA which doesn't have multiple CNs in DN. 

Another problem applies to both versions 2.0 and 2.2. There is no CRL checking 
performed during verification of documents (signatures made with revoked 
certificates appear to be valid for OpenOffice). Even CDP (CRL Distribution 
Points) field isn't shown when viewing certificate.

1. I have the same digital signature problem with Open Office Writer 2.2 and 
Entrust certificates published in the Microsoft Active Directory, which have 
the following DN structure:

cn=CA name
cn=Public Key Service
dc=Domain Component x
dc=Domain Component 2
dc=Domain Component 1

This problem doesn't exist in the Open Office Writer 2.0.

2. Also, I cannot find if Open Office Writer has the ability to perform a 
Certificate Revocation List (CRL) check.

I can send certificate and keys (PKCS#12 file) to assigned developer, so he/she 
can reproduce this problem.
Comment 6 joachim.lingner 2007-04-13 09:28:41 UTC
If this is a test certificate, than you could attach this file to this issue.
This would of course help. Thanks.

After applying all Windows XP patches, we managed to digitally sign a Writer 

But, what still remains a problem is that OpenOffice doesn't check for 
certificate revocation.
