Trying to change passwords on UNIX accounts stored in Win2K Active Directory... we
have extracted the Solaris 2.6 passwd binary and replaced 2.8 binary. However, still
get the following error:
# passwd dav
Permission denied
The following is logged in /var/adm/messages
Mar 25 20:09:18 sun6.CPQUNIX.NET passwd[11637]: [ID 280705 user.error] pam_ldap:
ldap_simple_bind Can't contact LDAP server
Using truss on passwd appears to show a dialog with the Win2K system running Active
Directory, Enterprise Certificate Authority via SSL, port 636. The reply from Win2K is
read on fd 5 and possibly compared with the local client database read on fd 4.
However, this leads to ldap_simple_bind failing.
We have exported the Microsoft Enterprise Certificate Authority certificate from the
Win2k system in base-64, DER and PKCS #7 format. The certificates have been copied to
the Solaris system. The certutil executable has been copied from another Solaris
system. However, attempts to add the Certificates to the database on Solaris fail as
follows:
# ./certutil -d /etc/ssl/certs -A -n "CPQ UNIX ENTERPRISE CA" -t "C,C,C" -i
cpqunix_der.cer
certutil: failure authenticating to key database.
: Security I/O error
Questions
1. how do we update the certifcate database on Solaris to include the Win2K Enterprise
CA?
2. what else do we need to do to get this working?
Although this is not OpenSSL it does appear to be an SSL issue, so any help
appreciated.
Thanks,
Stuart
Environment: Solaris 8, LDAP, SSL, Active Directory, Microsft SFU (Services For Unix)
