I´m following step by step Ricky´s guide "OpenLDAP + Samba Domain Controller On Ubuntu 7.10" (http://www.howtoforge.com/openldap-samba-domain-controller-ubuntu7.10) I´ve installed 7.10 just for be in the exact same situation that guide is. I´m having problems in the step of: # Enable the new LDAP Authentication Profile by executing the following command: When I run: "auth-client-config -a -p open_ldap" I get root@dc01-ubuntu:/etc/pam.d# auth-client-config -a -p open_ldap ** WARNING: Skipping 'open_ldap' (couldn't process) Usage: auth-client-config -p PROFILE -a -t TYPE [-dn -f FILE] auth-client-config -p PROFILE -a -t TYPE -r [-n -f FILE] auth-client-config -p PROFILE -a -t TYPE -s [-f FILE] auth-client-config: error: option -p: invalid choice: 'open_ldap' (choose from 'ldap_example', 'lac_ldap', 'kerberos_example') I´ve tryed ldap_example instead of open_ldap, but when I reboot I loose ssh access (As I´m working virtual I just got a snapshot back and didn´t loose all previous work). Do you know what´s happening there? Any help or suggestion?? Thanks a lot Facundo.
