Enabling SSL Connection with Internal Database on Existing Instance
This document describes the process to enable SSL connection with internal database on existing PKI instance.
WARNING: The NSS database does not support concurrent modification. To prevent database corruption, make sure all processes using the NSS database (e.g. DS or PKI server) are stopped before generating certificate requests, importing certificates, or removing certificates.
For new PKI instance, see Enabling SSL Connection with Internal Database on New Instance.
Make sure the DS is stopped:
$ systemctl stop dirsrv@<font color="red">localhost</font>.service
Store Directory Manager's password in pwdfile.txt:
$ echo <font color="red">Secret.123</font> > /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt $ chown <font color="red">nobody.nobody</font> /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt $ chmod 400 /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt
Store Directory Manager's password in pin.txt:
$ echo "Internal (Software) Token:<font color="red">Secret.123</font>" > /etc/dirsrv/slapd-<font color="red">localhost</font>/pin.txt $ chown <font color="red">nobody.nobody</font> /etc/dirsrv/slapd-<font color="red">localhost</font>/pin.txt $ chmod 400 /etc/dirsrv/slapd-<font color="red">localhost</font>/pin.txt
Set the NSS database password:
$ certutil -W -d /etc/dirsrv/slapd-<font color="red">localhost</font> -f /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt
Generate a certificate request for the new DS certificate:
$ PKCS10Client -d /etc/dirsrv/slapd-<font color="red">localhost</font> -p <font color="red">Secret.123</font> -a rsa -l 2048 -o ds.csr -n "CN=$HOSTNAME"
Restart the DS to allow the CA to process the request:
$ systemctl start dirsrv@<font color="red">localhost</font>.service
Submit the request for a new DS certificate signed by the CA:
$ pki -d /etc/dirsrv/slapd-<font color="red">localhost</font> ca-cert-request-submit --profile caServerCert --csr-file ds.csr
After approval, download the new DS certificate (this will be needed later):
$ pki cert-show <serial number> --output ds.crt
Download the CA certificate as well (this will also be needed later):
$ pki cert-show <serial number> --output ca.crt
Make sure the DS is stopped:
$ systemctl stop dirsrv@<font color="red">localhost</font>.service
Import the CA certificate downloaded earlier:
$ pki -d /etc/dirsrv/slapd-<font color="red">localhost</font> -C /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt \ client-cert-import "CA Certificate" --ca-cert ca.crt
Import the new DS certificate downloaded earlier:
$ pki -d /etc/dirsrv/slapd-<font color="red">localhost</font> -C /etc/dirsrv/slapd-<font color="red">localhost</font>/pwdfile.txt \ client-cert-import "DS Certificate" --cert ds.crt
Verify the import:
Certificate Nickname Trust Attributes
SSL,S/MIME,JAR/XPI
CA Certificate CT,C,C
DS Certificate u,u,u
Make sure the DS is started:
$ systemctl start dirsrv@<font color="red">localhost</font>.service
Enable secure connection with the following command:
dn: cn=RSA,cn=encryption,cn=config changetype: add objectclass: top objectclass: nsEncryptionModule cn: RSA nsSSLPersonalitySSL: DS Certificate nsSSLToken: internal (software) nsSSLActivation: on EOF
Optionally, disable insecure connection with the following command:
$ ldapmodify -x -D "cn=Directory Manager" -w <font color="red">Secret.123</font> << EOF dn: cn=config changetype: modify replace: nsslapd-allow-anonymous-access nsslapd-allow-anonymous-access: rootdse - replace: nsslapd-minssf nsslapd-minssf: 56 - replace: nsslapd-require-secure-binds nsslapd-require-secure-binds: on - EOF
Restart the DS server:
$ systemctl restart dirsrv@<font color="red">localhost</font>.service
Verify in DS error log (/var/log/dirsrv/slapd-localhost/errors) that the DS started succesfully with SSL:

Verify SSL connection with mozldap-tools and NSS database:
$ /usr/lib64/mozldap/ldapsearch -Z -h $HOSTNAME -p 636 \ -D "cn=Directory Manager" -w <font color="red">Secret.123</font> \ -P /etc/dirsrv/slapd-<font color="red">localhost</font> \ -b "<font color="red">dc=example,dc=com</font>" -s base "(objectClass=*)"
or with openldap-clients and DS certificate:
$ LDAPTLS_CACERT=ca.crt \ ldapsearch -H ldaps://$HOSTNAME:636 \ -x -D "cn=Directory Manager" -w <font color="red">Secret.123</font> \ -b "<font color="red">dc=example,dc=com</font>" -s base "(objectClass=*)"
or with openldap-clients and NSS databsae:
$ LDAPTLS_CACERTDIR=/etc/dirsrv/slapd-<font color="red">localhost</font> \ ldapsearch -H ldaps://$HOSTNAME:636 \ -x -D "cn=Directory Manager" -w <font color="red">Secret.123</font> \ -b "<font color="red">dc=example,dc=com</font>" -s base "(objectClass=*)"
Configure PKI server to use SSL by editing /var/lib/pki/pki-tomcat/<subsystem></subsystem>/conf/CS.cfg:
internaldb.ldapconn.host=<font color="red">server.example.com</font> internaldb.ldapconn.port=636 internaldb.ldapconn.secureConn=true
Restart PKI server:
$ systemctl restart pki-tomcatd@<font color="red">pki-tomcat</font>.service
Verify in DS access log (/var/log/dirsrv/slapd-localhost/access) that PKI server is connecting using SSL:
[29/Jun/2016:23:20:40] conn=36 fd=64 slot=64 SSL connection from <font color="red">server.example.com</font> to <font color="red">server.example.com</font> [29/Jun/2016:23:20:40] conn=36 TLS1.2 128-bit AES
Verify PKI server can communicate with the DS with the following command:
$ pki ca-cert-find
