Hello. I am planning to use the Fedora Directory Server in Redhat Linux ES4.0 to do 'Server Side Sorting'. The system processed around 4000 entries successfully. However, when the system tried processing more than 5000 entries, it returned an error such as 'LDAP_UNWILLING_TO_PERFORM'. Does anyone know how to fix this problem? Just in case, Ishow you the error logs below... --<Error Log>------------------------ [01/Mar/2007:14:07:15 +0900] conn=96 fd=68 slot=68 connection from 127.0.0.1 to 127.0.0.1 [01/Mar/2007:14:07:15 +0900] conn=96 op=0 BIND dn="" method=128 version=3 [01/Mar/2007:14:07:15 +0900] conn=96 op=0 RESULT err=0 tag=97 nentries=0 etime=0 dn="" [01/Mar/2007:14:07:15 +0900] conn=96 op=1 SRCH base="ou=Users,o=Section,o=Company" scope=1 filter="(uid=*)" attrs=ALL [01/Mar/2007:14:07:15 +0900] conn=96 op=1 SORT uid (*) [01/Mar/2007:14:07:16 +0900] conn=96 op=1 RESULT err=4 tag=101 nentries=1000 etime=1 notes=U [01/Mar/2007:14:07:17 +0900] conn=96 op=2 UNBIND [01/Mar/2007:14:07:17 +0 ----- Bellow, I done ------------------------------------------ 1.
