I'd like to request that a Password Modify ext. op. request should succeed on a LDAP connection as anonymous if the LDAP client provides the correct old password.

E.g. OpenDS implements it like this and it makes sense to me regarding a user setting a new password in case of an expired password.

Adding this feature would open up the pwdModify exop as a mechanism for password guessing attacks. In fact, in the next draft of the ppolicy spec I was intending to explicitly forbid this type of usage, to prevent such attacks.

The ppolicy spec provides for grace logins after a password is expired, to give users a few last opportunities to change their password. If they don't take advantage of those grace logins, then they are out of luck and must get help from a password administrator.

I'm going to reject this ITS.
