LDAP authorisation?

Hi, this is just an idea. We plan to set up some LDAP directory as addressbook. Maybe it's possible to make user authorisations via LDAP. I think I've heard abount a "pam_ldap" module. For linux this could work. Maybe there's some solution for Windows, too, maybe samba or Win2K. Can (Open-) LDAP be used as YP replacement? When useing MD5 hashes (shouldn't be a problem, I guess) it would be more secure than YP. Does anybody tried such things in practise? Is it stable or experimental stuff only? Is LDAP itself maybe a security problem? What are the disadvantages? oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
