Single sign-on with OCI Oracle connection gets ocijdbc12 error.

I'm trying to make a single sign-on connection from DG on windows to an Oracle DB.

When I use a "Thin" connection with user/pass everything works.
Database: Oracle (ver. Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options) Identifier case sensitivity: upper (plain), exact (delimited) Driver (JDBC4.0): Oracle JDBC driver (ver. 12.1.0.2.0)

But when I try to use "OCI" whith single sing-on I get the following error.

no ocijdbc12 in java.library.path

Any sugestions on how to solve this?

Using "Oracle [latest]"
