Rather then run the script,  I tried to run it for one example first

eastldap0:/opt/fedora-ds/alias#../shared/bin/certutil -d . -S -n
"Server-Cert-eastldap1" -s "cn=eastldap1.test.com" -c
"CA certificate" -t "u,u,u" -m 2000 -v 120 -8
eastldap.test.com,eastldap,eastldap1 -d . -z noise.txt -f pwdfile.txt
Generating key.  This may take a few moments...
eastldap0:/opt/fedora-ds/alias#../shared/bin/pk12util -d . -o
ywgldap1.isb.ec.gc.ca.p12 -n "Server-Cert-ywgldap1" -k pwdfile.txt -w
pwdfile.txt
pk12util-bin: PKCS12 EXPORT SUCCESSFUL

So at this point I had the .p12 file and the existing cacert.asc created,  and
sent them over to eastldap1.

Now the importing,

eastldap1:/opt/fedora-ds/alias# ../shared/bin/pk12util -d . -P slapd-eastldap1-
-i eastldap1.test.com.p12 -w pwdfile-0.txt -k pwdfile.txt
pk12util-bin: PKCS12 IMPORT SUCCESSFUL
ywgldap1:/opt/fedora-ds/alias# ../shared/bin/certutil -A -d . -P
slapd-eastldap1- -n "CA certificate" -t "CT,," -a -i
cacert.asc


Send over enable ssl ldif

ryan@infinity:~/fds-tools$ ldapmodify -x -h eastldap1 -D "cn=directory
manager" -W -f ssl_enable.ldif
Enter LDAP Password:
modifying entry "cn=encryption,cn=config"

modifying entry "cn=config"
ryan@infinity:~/fds-tools$ ldapmodify -x -h eastldap1 -D "cn=directory
manager" -W -f addrsa.ldif
Enter LDAP Password:
adding new entry "cn=RSA,cn=encryption,cn=config"

But when I restart slapd on eastldap1

Enter PIN for Internal (Software) Token:
[21/Sep/2007:17:52:33 +0000] - SSL alert: Security Initialization:
Can''t find certificate (Server-Cert) for family
cn=RSA,cn=encryption,cn=config (Netscape Portable Runtime error -8174 - security
library: bad database.)
[21/Sep/2007:17:52:33 +0000] - SSL alert: Security Initialization: Unable to

library: bad database.)
[21/Sep/2007:17:52:33 +0000] - SSL failure: None of the cipher are valid

Did I miss importing a private key from somewhere?  Do I need to use the
cacert.pfx I created in the basic steps?

Thanks
