Thanks!!! That's it! Like you said, I changed my TLSconfiguration.ldif file to point to "dn: cn=config" and it worked. I've once already seen the olcTLS* in the olcGlobal, however, I am new to LDAP backend database configuration, only used slapd.conf before. Thank you very much for the solution! I wish you a happy new year Belem ----- Ursprüngliche Nachricht ----- Von: Pierangelo Masarati Gesendet: 28.12.08 21:35 Uhr An: forumuser(a)online.de Betreff: Re: TLS config causes Object class violation olcTLSCACertificateFile belongs to olcGlobal, while you're trying to add it to a database object. Add it to cn=config instead. p. Ing.
