mkstore : ORA-01017: invalid username/password; logon denied : I am entering correct password.

A strange problem:

Oracle_home: 10.2.0.1
Oracle wallet connection is setup properly.

sqlplus username/password@connectstring works fine.

When we try to connect through wallet, Then it gives invalid username/password error.

sqlplus /@connectstring gives error :

ORA-01017: invalid username/password; logon denied

Password entered was correct.

as a workaround, use a tns connect string that is not 4, 8 or 12 bytes in length.
