I wanted to know if Teradata Drivers version 13.0 has any compatibility issue with Sun One Directory Server version 6.1.
Are you asking about support for LDAP authentication?
LDAP authentication support is actually a Teradata Database feature. You will want to refer to the Teradata Database "Security Administration" reference for your version of the Teradata Database.
You can find a link to the Security Administration manuals on this page:
In the Security Administration manual, go to the chapter titled "Directory Management of Database Users", and please refer to the section titled "Supported Directories".
