I am in a bad loop in trying to install a GoDaddy Cert in owncloud. Put my 3 certs in folder. Went to install and got. error 20 at 0 depth lookup:unable to get local issuer certificate │ │ Issues found while verifying the certificate chain: │ │ /var/lib/owncloud/admin/files/SSLCerts/certificate.pem: OU = Domain
To resolve this I had to combine the cert with itermediates . Ran openssl verify now on new certificate.pem and got the ok.
So tried again . This time the private_key does not match. So after running
openssl rsa -noout -modulus -in private_key.pem | openssl md5 and
ownCloud doesn't handle any certificates (except the ones for outgoing connections to external systems). In general its a job of your webserver.
How to configure such certificates are also not ownCloud specific so i would suggest to do some more research on the net outside of the scope of ownCloud. OpenSSL e.g. has some support resources listed at their webpage at [1]. If the initial message is showing up at your webservers logfiles a support forum dedicated to your webserver might be another possibility.
Owncloud doesn't seem to handle a lot of things it is supposedly capable of doing. Certificates, Active Directory, etc. Running this on Owncloud Appliance. Not sure how anything on appliance is not supported but will keep looking.
