Steps to Reproduce

1. Start up a clean instance Liferay Portal 6.2 
2. Set up an LDAP authentication
3. Navigate to Control Panel > Server Administration > Log Levels and set all classes related to LDAP to DEBUG​
4. Log in as an LDAP user
5. Observe that in the DEBUG logs, the java.naming.provider.url listed includes the three connection settings set by default in portal.properties

   java.naming.provider.url=ldap://localhost:10389, java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory, com.sun.jndi.ldap.connect.timeout=500, com.sun.jndi.ldap.connect.pool=true, java.naming.security.principal=cn=ldapadmin,dc=example,dc=com, java.naming.security.credentials=*******, java.naming.referral=follow, *com.sun.jndi.ldap.read.timeout=15000}

6. Shut down Liferay and upgrade the instance to DXP 7.2
7. In DXP 7.2, navigate to Control Panel > Server Administration > Log Levels and set all classes related to LDAP to DEBUG​
8. Log in as an LDAP user

Expected Behavior: In the debug logs, the java.naming.provider.url also contains the three connection properties

Actual Behavior: In the debug logs, the java.naming.provider.url does not contain the three connection properties

 java.naming.provider.url=ldap://localhost:10389, java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory, java.naming.security.principal=cn=ldapadmin,dc=example,dc=com, java.naming.security.credentials=********, java.naming.referral=follow}
