Error in Import Adaptive RFC Model

Question

Hi SDN,
I am trying to develop an application using Import Adaptive RFC Model, while creating a model i could not able to connect to the backend system after giving the single server parameters. When i click on the next button a pop up is displayed with an error message *"User Name or Password wrong" *.
But i could able to login to R/3 with the same userid and password from SAP logon pad.
Really i am at Six and Seven's to trace out this error. Please suggest me how to overcome this error and create the model succesfully.
Regards
Basha

Hi Praveen & Chaitanya
Thanks for your quick response and informative threads.
Actually in order to import an adaptive rfc model
I have right clicked the model node to create a model and given the model name,package name,model data and metadata names and clicked next button. Then in the next screen
Tab Strip -> Single Server:
Host name :
System Number :
client details:
Tab Strip -> Load balancing:
System :
Message Server:
System Name:
Group:
(in Tcode: SLMG i have added the group public also)
client details:
After entering the required details either in Single Server or Load balancing and clicked the next button  I could not able estabilish a connection to the backend R/3 and get the list of Bapi's or RFc's. Instead i am getting a pop up message "User Name or Password Wrong". I could not able to proceed from here.
But with the same above parameters i could able to logon to R/3 from SAP Logon Pad. I have tried by giving the user name in Cap's and small letters but no use.
As i was strucked at the intial step while creating the model but not during the execution of the program, as far as my knowledge is concerned i think we no need to worry on SLD or JCO connections during the creation of the model. Please correct me if i am wrong and suggest me to rectify the error.
