Dear Techies,

I do have small issue on connecting oracle server [odbc connection]
from .net [MOSS 2007 webpart]


This is the code snippet


public string strConString = "Driver={Microsoft ODBC for
Oracle};Server=myserver;Uid=system;Pwd=mypwd;";


using (OdbcConnection odbcCon = new OdbcConnection(strConString))
                {
                    odbcCon.Open();
                    strOrclCmd = " select * from customers";
                    OdbcDataAdapter odbcDA = new
OdbcDataAdapter(strOrclCmd, odbcCon);
                    DataSet ds = new DataSet();
                    odbcDA.Fill(ds);
                    return ds;



}


The above which is perfectly working fine with a console application.

The same code I have used in
System.Web.UI.WebControls.WebParts.WebPart which throws the below
exception....


System.Data.Odbc.OdbcException: ERROR [NA000] [Microsoft][ODBC driver
for Oracle][Oracle]ORA-12638: Credential retrieval failed

SQLSetConnectAttr failed
ERROR [01000] [Microsoft][ODBC Driver Manager] The driver doesn't
support the version of ODBC behavior that the application requested
(see SQLSetEnvAttr).

When I deploy the wep part in the sharepoint site through GAC, and
accessing site
throws the above error. Can anyone figure out which/where is going
wrong?
