Name or Password is incorrect (repeat logon) SAP RFC

Recently we have got a new application went to production environment and we stuck up with this issue in the production from RFC connector.

Error Information:


Type : SAP.Connector.RfcLogonException, SAP.Connector, Version=2.0.0.0, Culture=neutral, PublicKeyToken=50436dca5c7f7d23
Message : Name or password is incorrect (repeat logon)
Source : SAP.Connector
Help link :
ErrorGroup : RFC_ERROR_LOGON_FAILURE
ErrorCode : RFC_ERROR_LOGON_FAILURE
Data : System.Collections.ListDictionaryInternal
TargetSite : Int32 Open()
Stack Trace : at SAP.Connector.Connection.Open()
                                              


After several different tries changing passwords, Here is what we concluded to be on safer side while creating a password

1) Not more than 8 characters
2) No numbers, only alpha and all upper case

Once we reset our password to match the above criteria the RFCLogonException is gone and we are able to connect.
