In case you want to change the Yast Common Server Certificate to a Novell eDirectory signed one, follow this steps:

1. On the SLES server create the signing request without setting a pasword on it:

1. openssl rand -out /tmp/random.txt 1024
2. openssl genrsa -out server.key -rand /tmp/random.txt 1024
3. openssl req -new -key server.key -out server.csr

2. Next use iManager to issue a certificate using the signing request server.csr and export the certificate in base64 encoding.

3. Now export the public key of the eDirectory CA in base64 format

4. Next create a new cert.pem file containing the following:

-----BEGIN CERTIFICATE----- ... this is the block from the eDirectory CA public key ... -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- ... this is the server certificate signed by the eDirectory ... -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- ... this is the content of the server.key ... -----END RSA PRIVATE KEY-----

5. Now use openssl to create the pkcs12 file

1. openssl pkcs12 -export -in cert.pem -out cert.p12

6. Now start yast / security and users / common server certificate and import that new pkcs12 file cert.p12 and everything is done.

One side note: After the first tests I got always the message in yast that the certificate was imported, but the screen hasn't shown it. In the /var/log/YaST2/y2log I found the error "... invalid serial number ...". That serial number is from the eDirectory CA and I found no way to change it there. I think it was simply to long. I used a different eDirextory to sign it and then it worked.
