ftp and xdm authentication using ldap

Hello, We are trying to allow users to log in via ftp or XDM console to machines that are using LDAP authentication. Telnet and ssh are already working. PAM is installed and working (obviously). We are using Suse 7.1 (2.4 kernel) We would like to know which configuration file we need to create/modify to allow these two services to get authentication. Any hints? -- Andrew Petalik (OPS330, OPS440) http://cns.senecac.on.ca/~apetalik/
