UME Data sources can cause the authorization problems in portal ?

Hi,

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.

Your valuable ideas and experiences and expert comments are most welcome.
