DPOD includes an LDAP configuration script for easy configuration of DPOD to use an LDAP user registry.

The script uses a properties file to verify the configuration and update the configuration file and System Parameters. It can also disable the LDAP configuration in order to rollback to the internal database registry.

Properties File

A template of the LDAP properties file is provided at /app/utils/LDAP_parameters.properties.

It is recommended to backup the file before modifying it:

cp /app/utils/LDAP_parameters.properties /app/utils/LDAP_parameters.properties.orig

Edit the properties file and set the following properties based on the information that was collected in Planning LDAP Configuration:

Property	Description
dpod_ldap_method	Should be "user_attribute" (for scenario A) or "group_attribute" (for scenario B). e.g. "group_attribute"
test_user	The username of a user for testing e,g, "adminford"
test_user_password	The password of a user for testing e.g. "pass123"
connectionURL	Primary LDAP server URL. Use ldap:// prefix for non-SSL connection and ldaps:// prefix for SSL connection. e.g. "ldap://192.168.110.15:389"
alternateURL	Alternate LDAP server URL. Use ldap:// prefix for non-SSL connection and ldaps:// prefix for SSL connection. e.g. "ldap://192.168.110.16:389"
referrals	Follow or ignore LDAP referrals (follow/ignore) e.g. "ignore"
connectionName	Query user distinguished name (DN) e.g. "cn=LDAP Query User,ou=people,dc=example,dc=org"
connectionPassword	Query user password This password will be encrypted in the configuration file e.g. "pass123"
userBase	User base entry e.g. "ou=people,dc=example,dc=org"
userSubtree	User query sub-tree (true/false) e.g. "true"
userSearch	User search filter Operators (e.g. "&") are escaped (e.g. "&") {0} - a placeholder for the user name entered in the login screen e.g. "(&(objectClass=person)(sAMAccountName={0}))"
userRoleName	For scenario A only User entry attribute name e.g. "DPOD_Role"
roleBase	For scenario B only Group base entry e.g. "ou=groups,dc=example,dc=org"
roleSubtree	For scenario B only Role query sub-tree (true/false) e.g. "true"
roleSearch	For scenario B only Group search filter Operators (e.g. "&") are escaped (e.g. "&") {0} - a placeholder for the full DN of the authenticated user {1} - a placeholder for the user name of the authenticated user e.g. "(&(objectClass=groupOfUniqueNames)(uniqueMember={0}))"
roleNested	For scenario B only Nested groups (true/false) e.g. "true"
roleName	For scenario B only Group entry attribute name e.g. "cn"
LDAPConnectionURL	Primary LDAP server URL. Use ldap:// prefix for non-SSL connection and ldaps:// prefix for SSL connection. e.g. "ldap://192.168.110.15:389" (identical to the connectionURL property)
LDAPReferral	Follow or ignore LDAP referrals (follow/ignore) e.g. "ignore" (identical to the referrals property)
LDAPConnectionName	Query user distinguished name (DN) e.g. "cn=LDAP Query User,ou=people,dc=example,dc=org" (identical to the connectionName property)
LDAPConnectionPASSWORD	Query user password This password will be used just for testing, and will not be stored in System Parameters e.g. "pass123" (identical to the connectionPassword property)
LDAPUserBaseEntry	User base entry e.g. "ou=people,dc=example,dc=org" (identical to the userBase property)
LDAPUserSearchFilter	User search filter Operators (e.g. "&") are NOT escaped (e.g. "&") {0} - a placeholder for the user name entered in the login screen e.g. "(&(objectClass=person)(sAMAccountName={0}))" NOTE: This property is similar to the userSearch property, but is NOT identical.
LDAPGroupBaseEntry	Group base entry e.g. "ou=groups,dc=example,dc=org" (identical to the roleBase property)
LDAPGroupSearchFilter	Group search filter Operators (e.g. "&") are NOT escaped (e.g. "&") {0} - a placeholder for the user name of the authenticated user {1} - a placeholder for the full DN of the authenticated user e.g. "(&(objectClass=groupOfUniqueNames)(uniqueMember={1}))" NOTE: This property is similar to the roleSearch property, but is NOT identical.
LDAPGroupNameAttribute	Group name attribute' name e.g. "cn" NOTE: This property might be different than roleName property, depending on the chosen builtin roles scenario.

Testing LDAP Configuration

Before using the LDAP configuration script for the first time, please issue the following command:

cp /app/utils/LDAPUtilitiesTrustStore.jks /app/utils/LDAPtestTrustStore.jks

In order to test LDAP configuration, use the following command:

cd /app/utils/
/app/scripts/app_ldap_utilities.sh -f /app/utils/LDAP_parameters.properties

For a valid LDAP configuration the command's output should be:

INFO: Testing LDAP configuration...
INFO: LDAP configuration tests finished successfully.
INFO: The operation completed successfully.

For an invalid LDAP configuration, the command's output should be:

INFO: Testing LDAP configuration...
ERROR: LDAP parameters tests failed. Please check the log file, change the parameters and try again.
ERROR: The operation was aborted. See log file for more details.

Inspect the log file for detailed test failure messages. The log files are located in /logs/ui/app_ldap_utilities.log-<timestamp>.log.

Change the LDAP configuration in the properties file and rerun the script until tests are successful.

Updating LDAP Configuration

Once LDAP configuration has been tested and found valid, use the following command to perform the change in the configuration file and System Parameters:

cd /app/utils/
/app/scripts/app_ldap_utilities.sh -f /app/utils/LDAP_parameters.properties -u

Ensure DPOD's services are up and running before updating the LDAP configuration.

The command output should be:

INFO: Testing LDAP configuration...
INFO: LDAP configuration tests finished successfully.
INFO: Updating LDAP configuration...
INFO: Original configuration file /app/ui/MonTier-UI/conf/server.xml was backed up to /app/ui/MonTier-UI/conf/server.xml_2017-04-17_13-12-28
INFO: LDAP configuration has been updated, but has NOT been enabled. To enable it:
INFO:   1. Manually edit server.xml, comment DataSourceRealm and uncomment LDAPRealm.
INFO:   2. Manually set 'LDAP Connection Password' System Parameter using the UI.
INFO:   3. Manually set 'Enable LDAP' System Parameter to 'true' using the UI.
INFO:   4. Restart the UI service.
INFO: See the product documentation for more details.
INFO: The operation completed successfully.

After running this script, the LDAP configuration has been updated, but has not been enabled.

Follow the steps below to enable LDAP configuration.

Enabling LDAP Configuration

Enabling LDAP in Configuration File (server.xml)

Edit the server configuration file:

vi /app/ui/MonTier-UI/conf/server.xml

DPOD's internal database registry has to be disabled by commenting out the DataSourceRealm element:

<!--
<Realm className="org.apache.catalina.realm.DataSourceRealm"
...
/>
-->

Remove the comment that wraps the LDAPRealm element:

<Realm className="org.montier.common.tomcat.LDAPRealm"
...
/>

Enabling LDAP in System Parameters

Open the Web Console and navigate to System Parameters page [Manage→ System → System Parameters].

Manually set 'LDAP Connection Password' System Parameter with the query user password. In future versions this parameter will be automatically set by the LDAP configuration script.

Manually set 'Enable LDAP' System Parameter to 'true'.

Restart DPOD's Web Console

Restart DPOD's Web Console to make the LDAP configuration take effect.

Disabling LDAP Configuration

Use the following command to disable LDAP configuration in System Parameters:

/app/scripts/app_ldap_utilities.sh -d

Ensure DPOD's services are up and running before disabling the LDAP configuration.

The command output should be:

INFO: LDAP configuration has been disabled in System Parameters only. To fully disable it:
INFO:   1. Manually edit server.xml, uncomment DataSourceRealm and comment LDAPRealm.
INFO:   2. Restart the UI service.
INFO: See the product documentation for more details.
INFO: The operation completed successfully.

Disabling LDAP in Configuration File (server.xml)

Edit the server configuration file:

vi /app/ui/MonTier-UI/conf/server.xml

DPOD's internal database registry has to be enabled. To do that, remove the comment that wraps the DataSourceRealm element:

<Realm className="org.apache.catalina.realm.DataSourceRealm"
...
/>

Comment out the LDAPRealm element:

<!--
<Realm className="org.montier.common.tomcat.LDAPRealm"
...
/>
-->

Restart DPOD's Web Console

Restart DPOD's Web Console to make the LDAP configuration take effect.

Manually Inspecting LDAP Configuration

Inspecting LDAP Configuration in Configuration File (server.xml)

Edit the server configuration file and look for the LDAPRealm element. This element contains all the configuration set automatically by the script.

vi /app/ui/MonTier-UI/conf/server.xml

Inspecting LDAP Configuration in System Parameters

Open the Web Console and navigate to System Parameters page [Manage→ System → System Parameters].

The LDAP configuration system parameters are listed under "LDAP" category.
