I got it working by running authconfig on the Linux client and selecting LDAP for the authentication. It was set to MD5. Dave. Below is my original question Has anybody been able to configure a RHEL 3 or 4 machine as a client of a SunOne 5.2 Directory Server? I've got most of it working but I can't ssh or telnet into the RHEL machine. The symptom is I can't log into the Red Hat client as the ldap user (user80) using ssh it asks me for the password over and over martini@host:/home/martini[3]% ssh -l user80 redhatclient user80@redhatclient's password: user80@redhatclient's password: user80@redhatclient's password: My /etc/auto.master and /etc/auto.home files on the client looks like this [root@redhatclient init.d]# more /etc/auto.master # # $Id: auto.master,v 1.3 2003/09/29 08:22:35 raven Exp $ # # Sample auto.master file # This is an automounter map and it has the following format # key [ -mount-options-separated-by-comma ] location # For details of the format look at autofs(5). #/misc /etc/auto.misc --timeout=60 #/misc /etc/auto.misc #/net /etc/auto.net +auto.master [root@redhatclient init.d]# [root@redhatclient init.d]# more /etc/auto.home +auto.home [root@redhatclient init.d]# I can however do an su - user80 from the Red Hat client and that works and automounts do work as well. [root@redhatclient]# su - user80 [user80@redhatclient ~]$ df -k . Filesystem 1K-blocks Used Available Use% Mounted on nfsserver:/home/user80 4676672 3706464 923424 81% /home/user80 [user80@redhatclient ~]$ Is there anything on the LDAP server I should check?? I'm thinking this is a client issue with the /etc/ldap.conf file on the Red Hat machine. I remember when trying to log into a Solaris 9 client it didn't work until I switched to pam_ldap from pam_unix. Is the /etc/ldap.conf file on the Red Hat Client using pam_ldap? My /etc/openldap/ldap.conf file on Red Hat client looks like this [user80@eredhatclient openldap]$ more ldap.conf # # LDAP Defaults # # See ldap.conf(5) for details # This file should be world readable but not world writable. #BASE dc=example, dc=com #URI ldap://ldap.example.com ldap://ldap-master.example.com:666 #SIZELIMIT 12 #TIMELIMIT 15 #DEREF never HOST ldapserver.llnl.gov BASE dc=llnl,dc=gov Here is my /etc/ldap.conf file on the Red Hat Client The line that reads pam_password crypt is correct isn't it???? I did select crypt when configuring the LDAP server. Again, Solaris clients can log into themselves with ssh no problem. (NOTE) I HAVE NOT CONFIGURED TLS YET so in the file below I did not specify the use of tls/ssl. If anyone sees any possible errors in this file and or if you can let me know how yours looks that would be great. Thank You.
