Errors solman_setup initial configuration in StartSLD Configuration step

Question

Getting an authentication error when trying to sign into SAP netWeaver using the solman_admin account created in the first step of the initial configuration.  I tried going back and creating another user and setting a new password but am still getting the same User authentication failed.  I am able to sign in as the J2EE_ADMIN user id here and continue the configuration but get errors on step 66 of 137 Maintain SLD data supplier user.  Error: Name or password is incorrect.  I am able to click on in the error box the Step: Maintain SLD data supplier user which takes me into the J2EE Engine Useradministration.  In here I do not see the solman_admin userid if I try to create it I get the error Current suer has user creation permissions in the UME, but cannot create users in the back-end system (data source).  The original and possibly untranslated message was: "No active writeable datasource found for the user creation, check your Persistence Configuration." 
I do find my SLD data supplier user SLDDSUSER but am not sure what to fix here for step 66 noted above. 
Within Abap I am able to sign in as solman_admin successfully

Answer 1

As I said in my initial problem I cannot create the solman_admin in the UME.  I access the UME via   "http://cvlnxsp1.corp.cvpsnet.net:51000/webdynpro/dispatcher/sap.com/tcsecumewdumeadmin/UmeAdminApp" (J2EE Engine Useradministration)
What role or group do I need to give the J2ee_admin id to allow me to get around the error when clicking on create user in the UME
Current user has user creation permissions in the UME, but cannot create users in the back-end system (data source). The original and possibly untranslated message was: "No active writeable datasource found for user creation, check your Persistence Configuration.".
In ABAP I have given the j2ee_admin sap_all so I am assuming there is a role or group that j2ee_admin has to have in the UME?
