upgrade problems, can't query

[Tyler Retzlaff <rtr@softelsystems.com.au>]

After upgrading from openldap-2.0.27 to openldap-2.1.29 I can no  
longer query
(even anonymously) against my directory.  Basically I get:

log openldap-2.1.29:
Jul  6 00:06:16 gremlin slapd[4528]: conn=168 fd=126 ACCEPT from

err=32 text=
Jul  6 00:06:16 gremlin slapd[4528]: conn=168 fd=126 closed

which after reading the mailing list archives I understand err=32 to  
mean no such object?

Just for comparison I've attached an old log from before the upgrade,  
things look
almost identical except for a couple of lines that appear in the new  
log and
the uppercase bind params.  Oh and it works of course :)

log openldap-2.0.27:
Jul  3 00:12:08 gremlin slapd[3414]: daemon: conn=14 fd=7 connection

The configuration is identical, I haven't changed a thing.  The data  
is the same, I did
however back it up before upgrading.

Any advice would be greatly appreciated.

Thanks
