How can I change userid and loginid for LDAP as userdatabase in SAP EP ?

Hi all.

I have this situation.

one Windows Active Directory server.

one SAP EP server.

I needs to configure SAP EP server userinfo database point to Windows AD server.

In my Windows Active Directory, user attribute includes windowsuserid, physicaldeliveryofficename and others.

I needs to configure physicaldeliveryofficename as userid in SAP EP, but I needs user use windowsuserid as loginid to login in EP ( not physicaldeliveryofficename ) .

Is it possible ?

Now I can configure officename as userid and loginid in SAP EP, by change attributeMapping

<attributeMapping>

<principals>

<principal type="account">

<nameSpaces>

<nameSpace name="com.sap.security.core.usermanagement">

<attributes>

<attribute name="j_user">

<physicalAttribute name="physicaldeliveryofficename"/>

</attribute>

<attribute name="logonalias">

<physicalAttribute name="samaccountname"/>

</attribute>

<attribute name="j_password">

<physicalAttribute name="unicodepwd"/>

</attribute>

<attribute name="userid">

<physicalAttribute name="null"/>

</attribute>

</attributes>

</nameSpace>

</nameSpaces>

But in this way, user must enter their physicaldeliveryofficename as loginid.

I needs user to input their windows AD loginuserid to login in EP, is it possible ?

Thanks a lot
