Hi,

we are developing some Abap Webdympro to logon to an Abap system, release Netweaver 731, in order to allow our end user to logon via Internet browser to this system.

So our Abap system is acting like a Portal system, but it's not a J2EE system, it's just a Netweaver Abap system with the following components installed:

SAP_BASIS

SAP_ABA

PI_BASIS

ST-PI

IW_BEP

SAP_BW

UI2_700

UI2_701

UI2_702

UI2_731

UI2_FND

UI2_SRVC

UI5_731

UISAPUI5

UI_INFRA

No SSO is configured on the ABAP system, and no connection to the LDAP directory is in place , and it is neither  foresee.

In this moment we are able to login with the user-id of the user we created into the SU01, butt we would like to allow the access using the ALIAS of the users too.

The ALIAS of these users is like 'name.surname@mailaddres.com'.

We did some test but trying to logon we recive always the message:

"500 SAP Internal Server Error

ERROR: System logon form fields have invalid values (termination: ERROR_MESSAGE_STATE)"

On the network I'm able to find only post related to this issue using a J2EE portal, but nothing using an ABAP system as Portal.

Any idea ?

Regards
