I would like to configure ssl enabled ldap in my environment.I have already signed certificate and imported as per the Fedora wiki doc.when i restart dirsrv, i got the following error,

SSL alert: Security Initialization: Unable to find slot (Netscape Portable Runtime error -8127 - The security card or token does not exist, needs to be initialized, or has been removed.)
ERROR: SSL Initialization Failed.

Please let me know the solution for this.
