Problem: Removed the PreconfiguredUser login module from the "admin" security configuration. Now, logins to Sybase Control Center fail.
Solution: You must make the corresponding provider changes to the csi.properties file used to configure providers for Sybase Control Center. If changes are not coordinated, Sybase Control Center logins fail. See Configuring a Provider to Authenticate Sybase Control Center Logins in the Security guide for configuration details.
You can verify server-side configuration by trying to connect to Unwired Server from Unwired WorkSpace (requires creating Unwired Server Connection Profile with proper username and password among other things). If that works but the SCC login still fails, make sure the same configuration as in the 'admin' security configuration is also set in the Sybase Control Center CSI.properties file. The messages in agent.log can offer further clues on the issue.
