I'm really not sure if this will help, but here are the full instructions I used to get this working on a clean solaris 9 install (I haven't given it a shot on solaris 10 yet) Download the nspr, and nss packages for Solaris 9 here (http://sourceforge.net/project/showfiles.php?group_id=19386) and install them. Get Sun one Resource Kit here: http://www.sun.com/download/products.xml?id=3f74a0db And install it. Next run this command to setup your certificate database: # LD_LIBRARY_PATH=/usr/lib:/usr/local/lib ; export LD_LIBRARY_PATH # /opt/sunone/lib/nss/bin/certutil -N -d /var/ldap Add hosts entry to /etc/hosts for Ldap server, ** matching the certificate name ** (in my case, server-cert). You'll get this error, which will let you know the name you need to put in /etc/hosts: (I couldn't 'pull' it from the cert in any way) Feb 15 13:31:28 unknown sendmail[2061]: libldap: CERT_VerifyCertName: cert server name 'server-cert' does not match 'corporate-ds': SSL connection denied Get CA cert from directory using these commands: [root at corporate-ds alias]# pwd /opt/fedora-ds/alias [root at corporate-ds alias]# ../shared/bin/certutil -L -d . -n "CA certificate" -r > /root/cert.der Copy it to the solaris server, and import it with this: # /opt/sunone/lib/nss/bin/certutil -A -n "CA certificate" -i /export/home/mmont/cert.der -t "CTu,u,u" -d /var/ldap/ Run this command to set ldap client settings on the machine: # ldapclient -v manual -a authenticationMethod=tls:simple -a credentialLevel=proxy \ -a defaultSearchBase="dc=inside,dc=yourdomain,dc=com" \ -a domainName=yourdomain.com -a followReferrals=false \ -a serviceSearchDescriptor="netgroup: ou=netgroup,dc=inside,dc=yourdomain,dc=com" \ -a preferredServerList=10.5.1.18 -a serviceAuthenticationMethod=pam_ldap:tls:simple \ -a proxyPassword=blahblahblah -a proxyDn=cn=proxyagent,ou=profile,dc=inside,dc=yourdomain,dc=com Restart ldap.client: # /etc/init.d/ldap.client stop ; sleep 2 ; /etc/init.d/ldap.client start That should do it. Test settings with id, getent, or ldaplist: (You must be root, or sudo to use ldaplist) # ldaplist -l passwd yournamehere (This should list your entry in the ldap dir) I hope this helps someone, and I'm sure I'll attempt to get solaris 10 working at some point soon.
