Fixed In Version: 389-ds-base-1.3.3.1-1.el7 Doc Type: Bug Fix
Doc Text:
Cause: Modifying a password and explicitly settings the password storage scheme as a regular user(not as the Rot DN - "cn=directory manager"). Consequence: A user account can incorrectly modify another users password storage scheme. Fix: Only allow the root DN to change a user's password storage scheme. Result: User accounts can not change another user's password storage scheme.

Description Noriko Hosoi 2013-06-17 18:31:50 UTC
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47389

Steps:
. Using default password policy: stored in SSHA
. Give ACI to update all attributes including userpassword.
 aci: (targetattr ="*")(version 3.0;acl "allow all";allow (all) userdn="ldap:///anyone";)
.Let uid=tuser0 replace other user uid=tuser1's userpassword as follows:
{{{
 $ldapmodify ... -D "uid=tuser0,dc=example,dc=com" -w password << EOF
 dn: uid=Nuser1,dc=example,dc=com
 changetype: modify
 replace: userpassword
 userpassword: {CLEAR}newuser1
 EOF
}}}
Then, the tuser1's password is stored as a clear text.
{{{
 $ldapsearch ... userpassword
 dn: uid=Nuser1,dc=example,dc=com
 userpassword: newuser1
}}}
Expected result: Ordinary user should not be allowed to override the password policy.
