Hello Pierre. I have spent some time to setup authorization with LDAP via ypldap and want to share some ideas that I believe can help others. I think you can add it to documentation for ypldap with some details.
1. we should use ypbind in addition to ypldap. 2. we should activate YP passwd support in /etc/master.passwd with string: +:::::::::/bin/ksh 3. in /etc/rc script we should comment-out invocation of ypbind or it will launch before ypldap 4. we need login_ldap package for authentication As for 3 I think it is bad thing to modify rc script and we need some standard solution here! I have written post about it where I cover it in more details: [http://blogs.helion-prime.com/vasiliykiryanov/2009/05/07/authorization-with-ldap-on-openbsd.html] thanks, and have a nice day
