error in modifying subordinate entries
Hi,
I want to establish communication between two ldap servers at different machines.
For this i have used "ref attribute of ldap" by using this attribute, i am able to retrieve
entries of second ldap server. Means i can read or search entries of second server from
first ldap server.
But the problem comes when i want to modify any attribute of an entry of second server
from the first server.
Definitely i am having some access permissions related error.
Here i am attaching slapd.conf files of both ldap servers.
First Server slapd.conf:
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#

FIRST LADP SERVER DN:
fn=test_ref,fn=bioinfo,fn=gstorage,fn=gfs,dc=cdac,dc=in
where test_ref is having ref attribute
dn: fn=test_ref,fn=bioinfo,fn=gstorage,fn=gfs,dc=cdac,dc=in
objectClass: referral
objectClass: extensibleObject
fn: test_ref
ref: ldap://192.168.5.243/fn=test_ref,dc=cdac,dc=in
NOW SECOND LDAP SERVER is having DN:
dn: fn=test1,fn=test_ref,dc=cdac,dc=in
Now i want to delete "fn=test1,fn=test_ref,dc=cdac,dc=in" this entry.
I have used ldap command line tool "ldapdelete" and executed this tool on first LDAP machine.
Then the result of command is:
[root@tapti LDIF]# ldapdelete -x -h "tapti" -D "cn=Manager,dc=cdac,dc=in" \"fn=test1,fn=test_ref,fn=bioinfo,fn=gstorage,fn=gfs,dc=cdac,dc=in" -w "secret"
ldap_delete: Referral (10)
matched DN: fn=test_ref,fn=bioinfo,fn=gstorage,fn=gfs,dc=cdac,dc=in
referrals:
ldap://192.168.5.243/fn=test1,fn=test_ref,fn=bioinfo,fn=gstorage,fn=gfs,dc=cdac,dc=in

Please do me a favour suggest any solution as soon as possible through which i can update slave ldap server entries from master ldap server.
