Oracle Lite and OCI

Question

Is it possible to access Oracle Lite 10g using OCI. I am getting an error "ORA-24327: need explicit attach before authenticating a user" when trying to acces the Oracle Lite 10.3.0 using OCI. Can you please tell why it is occuring?

I am using the samples comming with Instant Client SDK.
Some of the relevant portion of the code is given below
static text username = (text ) "system";
static text password = (text ) "manager";
static text connectstring = (text ) "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = HOSTNAME)(PORT = 1521)) ) (CONNECT_DATA = (SID = POLITE)))" ;
errcode = OCIEnvCreate((OCIEnv **) &envhp, (ub4) OCI_DEFAULT,
(dvoid *) 0, (dvoid * (*)(dvoid *,size_t)) 0,
(dvoid * (*)(dvoid *, dvoid *, size_t)) 0,
(void (*)(dvoid *, dvoid *)) 0, (size_t) 0, (dvoid **) 0);
if (errcode != 0) {
(void) printf("OCIEnvCreate failed with errcode = %d.\n", errcode);
exit(1);
(void) OCIHandleAlloc( (dvoid *) envhp, (dvoid **) &errhp, OCI_HTYPE_ERROR,
(size_t) 0, (dvoid **) 0);
/* server contexts */
(void) OCIHandleAlloc( (dvoid *) envhp, (dvoid **) &srvhp, OCI_HTYPE_SERVER,
(size_t) 0, (dvoid **) 0);
(void) OCIHandleAlloc( (dvoid *) envhp, (dvoid **) &svchp, OCI_HTYPE_SVCCTX,
(size_t) 0, (dvoid **) 0);
(void) OCIServerAttach( srvhp, errhp, connectstring, strlen(connectstring), 0);
/* set attribute server context in the service context */
(void) OCIAttrSet( (dvoid *) svchp, OCI_HTYPE_SVCCTX, (dvoid *)srvhp,
(ub4) 0, OCI_ATTR_SERVER, (OCIError *) errhp);
(void) OCIHandleAlloc((dvoid *) envhp, (dvoid **)&authp,
(ub4) OCI_HTYPE_SESSION, (size_t) 0, (dvoid **) 0);
(void) OCIAttrSet((dvoid *) authp, (ub4) OCI_HTYPE_SESSION,
(dvoid *) username, (ub4) strlen((char *)username),
(ub4) OCI_ATTR_USERNAME, errhp);
(void) OCIAttrSet((dvoid *) authp, (ub4) OCI_HTYPE_SESSION,
(dvoid *) password, (ub4) strlen((char *)password),
(ub4) OCI_ATTR_PASSWORD, errhp);
checkerr(errhp, OCISessionBegin ( svchp, errhp, authp, OCI_CRED_RDBMS,
(ub4) OCI_DEFAULT));
The error I am getting is from this checkerr. For the HOSTNAME in the connectionstring I have given my machine IP. Please let me know your comments.
