How to read a file from Solaris-UNIX server using FILE adapte

Hi All,

I am able to send a file to the UNIX (samba file share) using BizTalk FILE adapter but getting the below error when trying to read a file using FILE adapter. The host user account has the full permissions on the UNIX file share, surprisingly error shows the windows account. 

 Error(error code)16397
Windows(R) Lightweight Directory Access Protocol (LDAP) failed a request to connect to Active Directory Domain Services(R) for Windows user <Domain\WindowsLogin>.
Without the corresponding UNIX identity of the Windows user, the user cannot access Network File System (NFS) shared resources.
 Verify that the Windows user is in Active Directory Domain Services and has access permissions.
Please advise.
Regards.
