Hi, I noticed in our directory server logs a number of queries which are not using indexes, and this appears to be down to sorting of the query being done the server side: ----- Server sorted------------- conn=1433 op=1 SRCH base="o=blah.com" scope=2 filter="(&(accountid=abc123)(objectClass=dnszone)(dnstype=soa))" attrs=ALL conn=1433 op=1 SORT dnszonename (4) conn=1433 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U ----- Not sorted ---------- conn=1440 op=1 SRCH base="o=blah.com" scope=2 filter="(&(accountid=abc123)(objectClass=dnszone)(dnstype=soa))" attrs=ALL conn=1440 op=1 RESULT err=0 tag=101 nentries=1 etime=0 The 'accountid' field is indexed but when doing server side sorting it seems to ignore this index - is this expected behaviour? What options do I have to ensure the index is used - just get the developers to sort the results in their code rather than on the server? Thanks. Jim.
