Can't get certificates installed on new server

I'm getting a generic error 80 when I try to use ldapmodify to configure my LDAP server to use a SSL certificate. Here is the LDIF I'm using:

dn: cn=config changetype: modify add: olcTLSCACertificateFile olcTLSCACertificateFile: /etc/ssl/certs/gd_bundle-g2-g1.pem - add: olcTLSCertificateFile olcTLSCertificateFile: /etc/ssl/private/wildcard.linaro.org.key - add: olcTLSCertificateKeyFile olcTLSCertificateKeyFile: /etc/ssl/certs/wildcard.linaro.org.crt

and the command:

ldapmodify -v -x -H ldapi:/// -f certinfo.ldif -D cn=admin,cn=config -W

Running logging at the highest level doesn't seem to give me much to go on ...

I've checked that the user that slapd is running under can read the three files.

Any suggestions or clarification on what I've overlooked?

Thanks.
