Back to UME logon screen when accessing WD applications (/nwa /useradmin)

[anboeh1]

After a Java Add-In installation to an existing CRM 5.0 system and the following upgrade of the J2EE to NW04s SPS09, none of the WebDynpro applications are working.When logging on to the WD based appplications (NWA, UME) the J2EE_ADMIN user is authenticated correct and then re-directed to the application, but then the UME logon page is displayed again. Security.log shows the logon to NWA of the J2EE_ADMIN user for example. It seems like the user is authenticated and re-directed "redirecting to /webdynpro/dispatcher/sap.com/tc_lmwebadmin_mainframewd/WebAdminApp" as expected but is then presented with a logon screen again.

J2EE_ADMIN# LOGIN.OK# USER.R3_DATASOURCE.J2EE_ADMIN# #

IP Address=[xxx]

Redirect:

/logon/logonServlet?redirectURL=%2Fwebdynpro%2Fdispatcher%2Fsap.com%2Ftc%7Elm%7Ewebadmin%7Emainframe%7Ewd%2FWebAdminApp

dev_dispatcher, dev_server0, defaultTrace.0, server.log, security.log are not containing any entries during logon attempts. Any solution hints or ideas where to search for further details / error analysis?

Thx in advance,

Hi,

Which persistence the UME is configured (DB / LDAP /ABAP). Check those configurations. Try log-in with user id "administrator". It may happen due to authorization also. To excatly find out the problem set the trace level for logger in visual admin and reproduce the issue.

Thanks

Hi R. Murali,

UME persistence is configured to ABAP productive client. (ume.persistence.data_source_configuration = dataSourceConfiguration_abap.xml

). The "administrator" user doesn't exist because it's a double stack installation, no Java only Stack. Tried diagtool (according SAP Note 957666) and the output shows nor errors, but a switch from J2EE_ADMIN authentication to J2EE_GUEST login:

...

J2EE_ADMIN | LOGIN.OK | USER.R3_DATASOURCE.J2EE_ADMIN | | IP Address=[10.7.80.142]

Redirect: /webdynpro/dispatcher/sap.com/tc_lmwebadmin_mainframewd/WebAdminApp

redirecting to /webdynpro/dispatcher/sap.com/tc_lmwebadmin_mainframewd/WebAdminApp

Entering method

Found uniqueID for logonId J2EE_GUEST

Exiting method with userAccount from cache
