Configuring maximum number of password attempts
Hi all, I am using freeradius to talk to an OpenLDAP server to validate passwords. This all works fine and dandy. If the user enters the right password they get in, if they enter the wrong password the don't. However, I can't find a way of locking out the user if they enter an invalid password three times in a row. I've trolled through the LDAP stuff but can't find anything in there. Is there a way I can create a password policy to do this? |\/|artin -- Senior Network Administrator, NEC (Europe) Ltd.

Not really, because FreeRADIUS is probably pulling the passwords out of LDAP, and doing the authentication itself. If FreeRADIUS is calling ldap to do the authentication, then maybe there's something in OpenLDAP to implement the password policy. Alan DeKok.

If you are just doing a bind to the ldap server for authentication, then, I think openldap is working on a password policy overlay that might get you what you want. I believe its only working on non-production versions right now. Not positive about that, but I remember a similar question to this in their mailing list. You may want to post your question to the openldap mailling list or search the archives of it.
Hi. From FreeRADIUS debug I can conclude that if first does search against LDAP with given username and base DN and then, if the search is successful, binds with given credentials. Both posixAccount and shadowAccount in LDAP does not have any attributes to count bad passwords and block users based no that. You can lock user with shadowAccount by butting LK in the beginning of his userPassword attribute value IIRC. But counting 3 or more bad passwords in a raw is a kind of extended logic here. There is an option for this in sambaSamAccount object class, but people complain that it is not working as promised. Just my 2 cents. A. Martin.Ward@uk.neceur.com wrote:
