hi all
today i want import a certificate from CAcert. i make it on the web, so i generate a csr, go to CAcert and generate a certifcate. i also download the root certifcate and the intermediate certificate. then i import all 3 .crt files (commercial.crt, cacert_root.crt, cacert_intermediate.crt) on the webgui but i only get this error:
Ihr Zertifikat konnte aufgrund eines Fehlers nicht installiert werden. : system failure: XXXXX ERROR: Unmatching certificate (/opt/zimbra/mailboxd/webapps/zimbraAdmin/tmp/current.crt) and private key (/opt/zimbra/mailboxd/webapps/zimbraAdmin/tmp/current_comm.key) pair.

What i make wrong? i have read some artikles with godaddy cert, but it dont want work. can someone give me a tip or help?
