Insufficient Access Rights

[Xinhuan Zheng]

I set up Self Service Password Tool. https://ltb-project.org/documentation/self-service-password. I configured a bind DN for password reset.

$ldap_binddn = "cn=proxyagent,ou=profile,dc=mycompany,dc=com";
$ldap_bindpw = "mypassword";

I'm getting "Password was refused by the LDAP directory (Insufficient access rights )" error when resetting a user's password. If I change the $ldap_binddn to "Directory Manager", it works.

I then added the "cn=proxyagent,ou=profile,dc=mycompany,dc=com" to "PD Managers" group with ACI:

ldapsearch -x -LLL -H ldap://server.mycompany.com:389  -s base -b 'ou=People,dc=mycompany,dc=com' aci
dn: ou=People,dc=mycompnay,dc=com
aci: (targetattr=*")(targetfilter ="(ou=People)")(version 3.0;acl "Engineering
  Group Permissions";allow (write)(groupdn = "ldap:///cn=PD Managers,ou=groups
 ,dc=mycompany,dc=com");)

ldapsearch -x -LLL -H ldap://server.mycompnay.com:389  -s base -b 'cn=PD Managers,ou=Groups,dc=mycompany,dc=com'  uniquemember
dn: cn=PD Managers,ou=Groups,dc=mycompany,dc=com
uniquemember: cn=Directory Manager
uniquemember: cn=proxyagent,ou=profile,dc=mycompany,dc=com

The "PD Managers" group has ACI to allow write for ou=People for all attributes. The proxyagent is member of the group. Why binding proxyagent results in "Insufficient Access Right"?

You are using the target filter incorrectly.  The targetfilter is used 
to evaluate an entry, so in this case the entry must have "ou: people" 
for access to be granted.  I think you are trying to use it as the 
target: all entries under ou=people,dc=your company.  Anyway you don't 
need it at all in this case, so just remove the targetfilter from the 
aci and it should start working as expected.

HTH,

Hi Mark,

You are right. I figure it out the ACI to add is:

(targetattr="userPassword") (version 3.0; acl "Allow proxyagent updating their password"; allow (write) userdn="ldap:///cn=proxyagent,ou=profile,dc=mycompany,dc=com";)

I used LDIF file to add above to the ACI attribute for 'ou=People,dc=mycompany,dc=com'

Thank you,
