pwdPolicySubentry is an operational attribute.  It will not be returned in search results unless you explicitly request it or use + in your requested attribute list.


If you change the add to a replace in your ldif file your modify operation should succeed.

I am trying to make sure my bind Service Account's password does not expire.  I set this in ou=Policies with the intention that the policy would only be applied to this user:


# Policies, domain

dn: ou=Policies,domain

ou: Policies

objectClass: organizationalUnit


# CustomBindAccountPolicy, Policies, domain

dn: cn=CustomBindAccountPolicy,ou=Policies,domain

objectClass: person

objectClass: top

cn: passwordDefault

cn: CustomBindAccountPolicy

sn: passwordDefault

pwdAttribute: userPassword

pwdMinAge: 0

pwdMaxAge: 0

pwdLockout: FALSE


However, I do not see this dn referenced on the user:


# importantuser, Service Accounts, domain

dn: uid=importantuser,ou=Service Accounts,domain

objectClass: top

objectClass: account

objectClass: posixAccount

objectClass: extensibleObject

uid: binduser

cn: bind

sn: user

givenName: binduser

title: Account

loginShell: /dev/null

uidNumber: 123

gidNumber: 456

homeDirectory: /dev/null

description: Service Account

userPassword:: password123


When I try to add using ldapadd and this ldif:


dn: uid=importantuser,ou=Service Accounts,domain

changetype: modify

add: pwdPolicySubentry

pwdPolicySubentry: cn=CustomBindAccountPolicy,ou=Policies,dc=davinci,dc=med,dc=cornell,dc=edu


I get this error:

me@nsa[~/ldap]$ ladd server.ldif                                                                                                                                                                                          

Enter LDAP Password: 

modifying entry "uid=importantuser,ou=Service Accounts,domain"

ldap_modify: Type or value exists (20)

        additional info: modify/add: pwdPolicySubentry: value #0 already exists


Do you have any idea what could be happening?  My ACL's allow the binduser to see everything so I don't understand what's happening.


Thank you very much!
