A DESCRIPTION OF THE PROBLEM :
Just add the parameter com.sun.jndi.ldap.connect.timeout for ldaps (ldap over ssl), i am getting the error, java.net.SocketException: Unconnected sockets not implemented.

It works fine for ldap without ssl.

A DESCRIPTION OF THE PROBLEM :
When i add the parameter com.sun.jndi.ldap.connect.timeout for ldaps (ldap over ssl), i am getting the error, java.net.SocketException: Unconnected sockets not implemented.

The error is hit when calling the function, InitialLdapContext
javax.naming.ldap.InitialLdapContext#InitialLdapContext(java.util.Hashtable<?,?>, javax.naming.ldap.Control[])

It works fine for ldap without ssl.

Tried with and without -Dcom.sun.jndi.ldapURLParsing=legacy results are no different.
-Djava.awt.headless=true -Djdk.attach.allowAttachSelf=true -Xms2048m -Xmx2048m -Dcom.sun.security.enableCRLDP=true -Dsun.net.inetaddr.ttl=30 -Dcom.sun.jndi.ldap.read.timeout=5000 -Dcom.sun.jndi.ldap.connect.pool.maxsize=200 -Dcom.sun.jndi.ldap.connect.pool.timeout=5000 -Dcom.sun.jndi.ldap.connect.pool.protocol=plain ssl -Dcom.sun.jndi.ldapURLParsing=legacy -Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

Same as - https://bugs.openjdk.org/browse/JDK-8173451?attachmentViewMode=list

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Set the parameter, com.sun.jndi.ldap.connect.timeout to a value like 30000
Create ldap connection over ssl




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
successful ldaps (ldap over ssl) connection should created.
ACTUAL -
Fails -

Caused by: javax.naming.CommunicationException: 9.30.92.253:18636 [Root exception is java.net.SocketException: Unconnected sockets not implemented]

CUSTOMER SUBMITTED WORKAROUND :
Don't set connection timeout which leads to indefinite waits and performance issues.
Switch to non SSL over ldap.

FREQUENCY : always
