UME Data sources can cause the authorization problems in portal ?
As per the SAP Help we can set up 3 type of data sources to portal.
1. User management of the AS ABAP
2. Data Base of the AS JAVA
3. Directory service ( LDAP ).
What are all the advantges and disadvantages of each type ?
Because I am using AS ABAP as Datasource. I had faced the problem while creating the users from portal Identity mangement.it had shown the error like
<b>An error occured during persistency.please contact your system administrator</b>. T
Then some one on forums told that it was the problem with UME data source.So for the time sake i had created the users from WAS.
Right now i am facing the problem with user authorisation in WEBGUI.
Every thing is working fine with my WINGUI. and all connection tests are also succesfull.and ITS services are also succesfully activated.
when i changed SAPGUI from WINGUI to WEBGUI in transactional Iview it showing the SAP WAS screen to enter credentials. after filling the valid credentials it showing the error like
<b>Client, name, or password is not correct; log on again</b>
I thought it may be the problem with the ABAP datasource.
