TLS failure when running OpenLDAP 2.3.30 on Debian 4.0

Hello,

I just upgraded to Debian 4.0 and OpenLDAP 2.3.30 and have some problems
starting slapd afterwards.

With TLS enabled I get this output in syslog when
running /etc/init.d/slapd start:

Aug 10 10:27:43 localhost slapd[10057]: daemon: IPv6 socket() failed
errno=97 (Address family not supported by protocol) 
Aug 10 10:27:43 localhost slapd[10057]: /etc/ldap/slapd.access: line 11:
rootdn is always granted unlimited privileges. 
Aug 10 10:27:46 localhost slapd[10057]: main: TLS init def ctx failed:
-1 
Aug 10 10:27:46 localhost slapd[10057]: slapd stopped. 
Aug 10 10:27:46 localhost slapd[10057]: connections_destroy: nothing to
destroy. 

If I disable TLS slapd starts without any errors. Any clue what the 
"main: TLS init def ctx failed:" means is appreciated. 

Thanks,

Erling
