Rich, et al, hello. Thanks to everybody for all the help to date -
quite incredible really. I've done my research but have nothing positive to report. I believe I was mistaken when I thought I could simply configure nss_ldap/pam_ldap to use a client SSL cert when binding to FDS : http://www.nabble.com/Using-certificate-per-host-to-secure-communication-to-OpenLDAP-td19371786.html http://www.nabble.com/Using-tls_cert-key-without-rootbinddn-td9089498.html Apparantly the secure tunel is used, the OS's certificate is 'validated' by FDS but no LDAP bind is performed. I reckon we'll put the password, in clear text, in the file /etc/ldap.conf and protect the file. Also, I think one must leave the client's (Linux O/S) secret key-file without a password. Cdlt, Dave -------------- Rich, hello and, as ever, thanks for the helpful reply. One very quick question andI have no idea - all I know is that if you need a password to unlock the private key, you need to store it somewhere.a quick technote 'for the record'.< You write, '... It probably won't, unless you either hardcode the clear text password ...' Q1: Hardcode where ? Is there an attribute in /etc/ldap.conf specifically for the keyfile password ? < You write, '... or simply have no key password ...' For the record, I reckon I need the '-noDES' option if I don't want a key file password: openssl req -newkey rsa:1024 -keyout ${FN}.key -out ${FN}.csr -days 7300 -nodes <<EOFOk. Thanks again,...
