I am trying to connect 12c database  through PowerBuilder 2017 R3

with following code 

if not IsValid (SQLADM) then
SQLADM = create n_tr
end if

ls_logon_user_prefix = this.of_prefix(as_userid)

SQLADM.of_Init(is_AppINIFile, "Database")
SQLADM.logid = ls_logon_user_prefix
SQLADM.logpass = ls_encrypt_passwd

IF SQLADM.of_Connect() <> 0 THEN
ls_encrypt_passwd = this.of_encryption_old(0, this.is_userseed, as_password) // 0 - encrypt
ls_encrypt_passwd = this.of_prefix(ls_encrypt_passwd) // add prefix if required
SQLADM.logpass = ls_encrypt_passwd
IF SQLADM.of_Connect() <> 0 THEN
MessageBox('Error Msg', SQLADM.SQLErrText)
return -1
end if

getting the following message

ORA-01017: invalid username/password; logon denied

But Same code if I try to connect to oracle 11g database its working perfectly fine.

Thanks
