Issue : Unable to Sign In into presentation services and RPD obiee 11 
Solution: refresh the GUID.A refresh forces the system to reference the user GUID contained in the new directory server. Authentication errors may result if the GUIDs are not refreshed and the system detects a mis-match for the user GUID.


Here are steps how to refresh the GUID's:


To refresh the user GUIDs:


1. Open the NQSConfig.INI file for editing.Locate the setting FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = NO and change its value to YES.


2. Modify the instanceconfig.xml file to instruct Oracle BI Presentation Server to refresh GUIDs on restart. Edit the file to add the last line in the following instruction


3. <ps:Catalog xmlns:ps="oracle.bi.presentation.services/config/v1.1"> <ps:UpgradeAndExit>false</ps:UpgradeAndExit> <ps:UpdateAccountGUIDs>UpdateAndExit</ps:UpdateAccountGUIDs>


4. From a terminal window, stop and restart the managed processes using the opmnctl parameters stopall and startall.


5. Edit the NQSConfig.INI file to reset the FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = YES to NO and restart the Oracle BI Servers.


6. Remove, set to none, or comment out the line (see UpgradeAndExit in the following example) added to the instanceconfig.xml file (that instructs Oracle BI Presentation Server to refresh GUIDs on restart).
<ps:Catalog xmlns:ps="oracle.bi.presentation.services/config/v1.1">
<ps:UpgradeAndExit>false</ps:UpgradeAndExit>
<ps:UpdateAccountGUIDs>none</ps:UpdateAccountGUIDs>
Restart the Presentation Server for the instanceconfig.xml file that was updated.


7.Make sure Oracle WebLogic Server and the system components are also running, if they are not running, restart them.
