SUP: different user/password for different System

Hi all,

i'm developing an application with Sybase unwired Platform and i have a problem,

in a Sup application is possible connect heterogenous systems like a SAP RFC and a webservices,

but if my user for the sap system is different from the webservice's one, how can i store the different credentials?

I could attach the ldap authentication but the user on ldap would be correct only for one of the system.

Can you help me?
