Changes to ACIs

The following changes have been made to ACIs in Directory Server 6.2.

Changes in the ACI Scope

In Directory Server 5.2 ACIs on the root DSE had base scope. In Directory Server 6.2, ACIs on the root DSE have global scope by default, equivalent to targetscope="subtree".

To reproduce the same behavior as Directory Server 5.2, add targetscope="base" to ACIs on the root DSE. If you use dsmig to migrate the configuration, this is done automatically.

Changes in Suffix-Level ACIs

In Directory Server 5.2, the following ACI was provided, at the suffix level:

aci: (targetattr != "nsroledn || aci || nsLookThroughLimit || 
  nsSizeLimit || nsTimeLimit || nsIdleTimeout || passwordPolicySubentry || 
  passwordExpirationTime || passwordExpWarned || passwordRetryCount || 
  retryCountResetTime || acc ountUnlockTime || passwordHistory || 
  passwordAllowChangeTime")(version 3.0; acl "Allow self entry modification 
  except for nsroledn, aci, resource limit attributes, passwordPolicySubentry 
  and password policy state attributes"; allow (write)userdn ="ldap:///self";)

This ACI allowed self-modification of user passwords, among other things. This ACI is no longer provided in Directory Server 6.2. Instead, the following global ACIs are provided by default:

aci: (targetattr != "aci") (targetscope = "base") (version 3.0; 
aci "Enable read access to rootdse for anonymous users"; 
allow(read,search,compare) user dn="ldap:///anyone"; )

aci: (targetattr = "*") (version 3.0; acl "Enable full access 
for Administrators group";  allow (all)(groupdn = 
"ldap:///cn=Administrators,cn=config"); )

aci: (targetattr = "userPassword") ( version 3.0; acl "allow 
userpassword self modification"; allow (write) userdn = "ldap:///self";)

In Directory Server 6.2, the default userPassword ACI at root DSE level provides equivalent access control to the default 5.2 ACI at suffix level. However, if you want to reproduce exactly the same access control as in 5.2, add the following ACI to your suffix. This ACI is the 5.2 ACI, with the new password policy operational attributes for Directory Server 6.2.

aci: (targetattr != "nsroledn || aci || nsLookThroughLimit || 
  nsSizeLimit || nsTimeLimit || nsIdleTimeout || passwordPolicySubentry || 
  passwordExpirationTime || passwordExpWarned || passwordRetryCount || 
  retryCountResetTime || accountUnlockTime || passwordHistory || 
  passwordAllowChangeTime || pwdAccountLockedTime || pwdChangedTime || 
  pwdFailureTime || pwdGraceUseTime || pwdHistory || 
  pwdLastAuthTime || pwdPolicySubentry || pwdReset")(version 3.0; acl "Allow self entry modification 
  except for nsroledn, aci, resource limit attributes, passwordPolicySubentry 
  and password policy state attributes"; allow (write)userdn ="ldap:///self";)

Do not allow users write access to everything and then deny write access to specific attributes. Instead, explicitly list the attributes to which you allow write access.
