What's a good source of documentation on ldap and unix 
domain sockets?  I see it mentioned, but only briefly 
in the slapd man page.

I find only one mention of ldapi in the OpenLDAP 
Administrator's Guide and it's not explanatory.

I find no mention of it at all in the FAQ-O-Matic, and 
no explanatory mentions of it by searching the list 
archives.

Thanks in advance for any suggestions and thanks very 
kindly for all the responses in this thread thus far.
