[389-users] Chaining and LDAP_UNWILLING_TO_PERFORM problem

Wed Jul 15 16:56:00 UTC 2009

Hi,

i try to configure 2 Directory Server with db link.

I have first DS that point to second DS that have DB in filesystem.

I create a proxy user in second DS:

# tproxy, config
dn: uid=tproxy,cn=config
uid: tproxy
givenName: test
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetorgperson
sn: proxy
cn: test proxy
userPassword:: *********************************************

and i create in first DS the "Dababase link" that use this user to bind
in second DS.

In second DS i add the following aci:

(targetattr = "*") (target = "ldap:///dc=example,dc=com") (version
3.0;acl "AciChepermettetutto";allow (all)(userdn =
"ldap:///uid=tproxy,cn=config");)

(targetattr = "*") (target = "ldap:///dc=example,dc=com") (version
3.0;acl "proxy acl";allow (proxy)(userdn = "ldap:///uid=tproxy,cn=config");)

Bu if i try to execute the ldapserach in first directory server i have
the following error:

dapsearch -h localhost -x -p 20389 -D "cn=Directory Manager" -w
********* -b "dc=example,dc=com" "(objectclass=*)"
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 53 Server is unwilling to perform
text: Proxy dn should not be rootdn

# numResponses: 1

If i enable verbose logging in my error log i have:

The problem seems the "ACL preoperation" plugin. Indeed if i disable
this plugin, it WORKS.
But i cannot disable this plugin.

Any ideas to solve the problem??

Thanks and sorry in advance for my bad English
