Hi, I have configured vsftpd on a RHEL 4 server box. Have configured Kerberos to work with the Windows 2003 Active Directory server and using the kinit & klist command verify that the Kerberos authentication is working. What I would like to do is : Only for vsftpd the authentication should be against the Active Directory, Below is the output of the /etc/pam.d/vsftpd -------------- [root@ftp ~]# cat /etc/pam.d/vsftpd #%PAM-1.0 auth?????? required???? pam_krb5.so try_first_pass auth?????? required???? pam_shells.so account??? required???? pam_krb5.so try_first_pass session??? required???? pam_krb5.so try_first_pass session??? required???? pam_loginuid.so [root@ftp ~]# -------------- Output of klist command -------------- [root@ftp ~]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: test2@GOTEST.COM Valid starting???? Expires??????????? Service principal 02/08/06 12:56:55? 02/08/06 22:56:56? krbtgt/GOTEST.COM@GOTEST.COM ??????? renew until 02/09/06 12:56:55 Kerberos 4 ticket cache: /tmp/tkt0 klist: You have no tickets cached [root@ftp ~]# -------------- Please let me know what will be the new entries in the /etc/pam.d/vsftpd file and whether any other file is to be edited ? Kindly help. Regards, Vijay
