Ok, so what you want to do is issue the certificate once, then perhaps 
move it to other directories? If so here is what you do:

1. Generate a new database (or use an existing one, it doesn't really 
matter).
2. generate your Certifiacte Server Request (CSR)
3. Sign this with your CA
4. Import the new server certificate into your database (certutil -A ...)
5. Export this server cert, which I've nicknamed Server-Cert, into a 
PKCS#12 file with:

pk12util -o server.p12 -n Server-Cert -P slapd-foo- -d alias

6. You can now import this into another certificate database with

pk12util -i server.p12 -n Server-Cert -P slapd-bar- -d alias-test1

The other alternative is to simply copy the database files between 
directories, but you'll pick up all certificates/keys rather than 
discretely copying a single cert/key combo.
