Hi, I'm currently butting my head on a configuration where I have a RHEL4 (x86_64) server with OpenLDAP and proftpd, user data are residing in the OpenLDAP, and I wish to get proftpd to also use that LDAP directory. 2 variants: - recompile proftpd with LDAP support built-in. This is definitely not wanted for maintainability reasons, I need to use plain RPMs from RedHat. I did install proftpd-ldap, but for some reason proftpd won't recognize the presence of that module. - get proftpd to use PAM, specifically pam_ldap I went with the 2nd variant, but didn't get it working so far. According to the fine manuals, I've created the file /etc/pam.d/ftp with contents like: auth sufficient /lib64/security/pam_ldap.so account sufficient /lib64/security/pam_ldap.so session sufficient /lib64/security/pam_ldap.so (I did try with some other variants). proftpd.conf is adapted: AuthPAM on AuthPAMConfig ftp AuthOrder mod_auth_pam.c* mod_auth_unix.c The files /etc/ldap.conf resp. /etc/openldap/ldap.conf are adapted for use with the local LDAP, and simple ldapsearch -x uid=xyz does provide the correct answer. nsswitch was of course adapted. I can login via ssh with an user present only in the LDAP tree, but no dice with proftpd. All I find in the log file is "no such user" despite activating "debug" logging. The ldap log doesn't show activity at the moment of trying to access proftpd. Any ideas what I missed? I'll welcome precise RTFM instructions, google or proftpd.org are what got me this far. Greetings & TIA, Eric
