Good point. The problem is that the NSS interface doesn't allow for such things so you would have to use pam_ldap for all authentication (no big deal just a minor PITA to change all the /etc/pam.d files and keep them maintained). Then what we need is an option for pam-ldap to specify which filter should be used. -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
