chronic ldapsearch failure

[Jon Roberts <jon@mentata.com>]

I am running RH Linux 7.2 and OpenLDAP 2.1.12 with ldbm/gdbm backend. It 
appears to load data properly with slapadd and export with slapcat. 
However, I am unable to find anything with ldapsearch. No matter what 
arguments I give, I get:

ldap_sasl_interactive_bind_s: No such attribute (16)

In my log output (loglevel 256), for each search attempt I get:

Feb 18 15:27:03 grover slapd[1276]: conn=1 fd=9 ACCEPT from 
IP=127.0.0.1:32785 (IP=0.0.0.0:389)
Feb 18 15:27:03 grover slapd[1319]: conn=1 op=0 SRCH base="" scope=0 
filter="(objectClass=*)"
Feb 18 15:27:03 grover slapd[1319]: conn=1 op=0 RESULT tag=101 err=0 text=

I was able to search from a remote mail client, so I know the data is in 
there.

Perhaps related, I get the following in the log each time I start slapd:

Feb 18 15:20:06 grover slapd[1272]: daemon: socket() failed errno=97 
(Address family not supported by protocol)

Any help would be appreciated.
