Directory Server Control Center certificates
Make sure to setup Directory Server Control Center certificates
For a list of steps on how to configure the DSCC certificates Click Here (This is needed for DSCC replication)
Before you begin
Make sure your storage is setup with the correct block size check this first Directory Server Databases and Usage of db_stat
Another place to look on how to tune the files system is Filesystem Cache Optimization Strategies
Directory Proxy configuration
Create a Directory Proxy
dpadm create -p 389 -P 636 -D "cn=Proxy Manager" -w pwfile /data1/ldaproxy
Start the Directory Proxy instance
dpadm start /data1/ldaproxy
Request a self sign certificate
dpadm request-cert /data1/ldaproxy ldaproxy1
Install the self sign CA certificate
dpadm add-cert /data1/ldaproxy my-ca /tmp/ca.cert
Install self sign certificate
dpadm add-cert /data1/ldaproxy ldaproxy1-cert /tmp/new.cert
At this point we would have a self sign working certificate with owner own CA certificate installed add to our proxy instance.
To get the directory proxy CA certificate run
The certificate is needed for the load balancer (NetScaler) to be able to connect to the Directory proxy’s
dpadm show-cert -F ascii /data1/ldaproxy
Proxy Server configuration tuning and changes
Heap Memory tuning (restart reqierd)
Change the proxy to use 2048M memory (from default 256M)
dpadm set-flags /data1/ldaproxy jvm-args="-Xmx2048M -Xms2048M -XX:NewRatio=1 -XX:+PrintGCDetails -Xloggc:/var/java/java-gc.log -XX:NewSize=1024M -XX:MaxNewSize=1024M -XX:PermSize=128M -XX:MaxPermSize=128M -XX:SurvivorRatio=32 -XX:MaxLiveObjectEvacuationRatio=15 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+PrintGCTimeStamps -Dsun.security.pkcs11.enable-solaris=false" Verify the change: dpadm get-flags /data1/ldaproxy Restart for the change to take affect dpadm restart /data1/ldaproxy
Directory Proxy configuration
Setup the Directory Proxy destinations
Crate a password file (used by the whole configuration) and setup the destinations
echo 'password'>/tmp/pw On proxy1: dpconf create-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap1-389" ldap1.domain.com:389 dpconf create-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap1-636" ldap1.domain.com:636 dpconf create-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap2-389" ldap2.domain.com:389 dpconf create-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap2-636" ldap2.domain.com:636 On proxy2: dpconf create-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap1-389" ldap1.domain.com:389 dpconf create-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap1-636" ldap1.domain.com:636 dpconf create-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap2-389" ldap2.domain.com:389 dpconf create-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap2-636" ldap2.domain.com:636
Setup the Directory Proxy LDAP Pools
On ldaproxy1: dpconf create-ldap-data-source-pool -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "DataSource-Pool" On ldaproxy2: dpconf create-ldap-data-source-pool -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "DataSource-Pool"
Assign the pools to destinations
Assign the pools to LDAP destinations
On ldaproxy1: For both secure and non secure run dpconf attach-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-389" "ldap1-636" "ldap2-389" "ldap2-636" Note: For both secure only non secure rnn: dpconf attach-ldap-data-source -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-636" "ldap2-636" On ldaproxy2: For both secure and non secure run: dpconf attach-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-389" "ldap1-636" "ldap2-389" "ldap2-636" Note: For both secure only non secure run: dpconf attach-ldap-data-source -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-636" "ldap2-636"
Setup your LDAP views
Create your LDAP views and assign the pool to use
On ldaproxy1: dpconf create-ldap-data-view -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "View" "DataSource-Pool" dc=domain,dc=com On ldaproxy2: dpconf create-ldap-data-view -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "View" "DataSource-Pool" dc=domain,dc=com
Enable the data sources
Finaley we needed to enable the data source and restart the proxy server for the LDAP connection pools to work
dpadm restart /data1/ldaproxy
Disable Non secure data source (if not used)
dpconf set-ldap-data-source-prop -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap1-389" is-enabled:false dpconf set-ldap-data-source-prop -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "ldap2-389" is-enabled:false dpconf set-ldap-data-source-prop -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap1-389" is-enabled:false dpconf set-ldap-data-source-prop -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "ldap2-389" is-enabled:false
Set the Directory Proxy weight
dpconf set-attached-ldap-data-source-prop -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-636" add-weight:50 bind-weight:50 compare-weight:50 delete-weight:50 modify-dn-weight:50 modify-weight:50 search-weight:50 dpconf set-attached-ldap-data-source-prop -i -h ldaproxy1.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap2-636" add-weight:50 bind-weight:50 compare-weight:50 delete-weight:50 modify-dn-weight:50 modify-weight:50 search-weight:50 dpconf set-attached-ldap-data-source-prop -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap1-636" add-weight:50 bind-weight:50 compare-weight:50 delete-weight:50 modify-dn-weight:50 modify-weight:50 search-weight:50 dpconf set-attached-ldap-data-source-prop -i -h ldaproxy2.domain.com -P 636 -w /tmp/pw "DataSource-Pool" "ldap2-636" add-weight:50 bind-weight:50 compare-weight:50 delete-weight:50 modify-dn-weight:50 modify-weight:50 search-weight:50

Setup Solaris (SMF) services and Auto restart
To autostrat/stop for the Directory Proxy
Note: Need to run this when the instance is down
dpadm enable-service -T SMF /data1/ldaproxy-config
Problems and resolution doing directory proxy configuration
Problem 1
Problem: Connections time out with error’s of LDAP to quick disconnect
- Problem: Getting error “connection idle time-out has expired” in the access log
Solution: Modify conf.ldif from milliseconds to seconds
Solution: Set this in the /data1/ldaproxy1/config/conf.ldif on port 389/636 from 3600 milliseconds (3 seconds) to 3600000 milliseconds
Note: This is reference as seconds but relay is milliseconds
From: connectionIdleTimeOutInSec: 3600 To: connectionIdleTimeOutInSec: 3600000
Enable all LDAP controls to pass Directory Proxy
To allow all controls true the proxy run this then restart

Setup Directory and Proxy Server Monitoring
Sun Directory and Directory proxy server Monitoring
Note: You can not install the Monitoring Server and Client on the same server (or it will not work)
Run the JES installer and select Sun Monitoring Console version 1.0 on the Monitoring Server
On the monitoring server setup the Console
/opt/SUNWmfwk/bin/mfwksetup -i /opt/SUNWmfwk/bin/masetup -i
On all Directory Servers and Proxy Servers enable the monitor plugin to be able to monitor it and restart
Login to the Monitoring Console server and click on Sun Monitoring Console
In discovery enter the IP or Host of the Directory client to Monitor.
