thanks

[re-sending with text wrapping, sorry]

Hello, 

I noticed that during bootup, when the /etc/init.d/slapd script returns, the 
LDAP server is not fully available. I noticed this because, right after, I have 
my DHCP server (isc-dhcp-server) starting, and the dhcp configuration 
configuration is within the local LDAP tree. But, on bootup, dhcp fails to 
start because it cannot connect to the LDAP server: 

-----------
dhcpd: Error: Cannot login into ldap server localhost:389: Can't contact LDAP server
dhcpd: Configuration file errors encountered -- exiting
[...]
dhcpd: exiting
-----------

Of course, everything works if I just try to start dhcp manually after bootup. 

It is probably necessary to add in the /etc/init.d/slapd script, either a 
"sleep 2" or more, either a detection of the "readyness" of the slapd daemon. 
One could also patch the slapd server, so it could handle this situation 
itself.
