Hi, I've just ran in to the same problem described in this bug: https://bugs.openjdk.java.net/browse/JDK-8149521
I found it in java7u79 and I used java8u91 to confirm it still exists. The error is in "com.sun.jndi.ldap.ServiceLocator" at line 273 (http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/df209f221cca/src/share/classes/com/sun/jndi/ldap/ServiceLocator.java), The "Hostname" token always has a trailing "." (period). This doesn't normally matter for "normal" network operation but it is critical where working with Kerberos. If you use "ldap:///dc=example,dc=com"; the the corresponding name might be something like "ldap1.example.com."(notice the trailing dot) Kerberos is then looking for "ldap/ldap1.example.com." instead of "ldap/ldap1.example.com" The first record simply doesn't exist in the kerberos DB. Regards, Bill Mair
