How to distinguish between internet & intranet user?

[Former Member]

Hi,

we are on EP6 sp13.

we have 2 types of scenarios:

1) users logging from internet

2) users logging from intranet

>>>>>>> 1) user from internet will access the portal as follows:

https://sap1.name1.ae:8443/irj/portal(where 8443 -- https port of the webdispatcher)

>>>>>>> 2) user from intranet will access the portal as follows:

http://sapportal.domainname.net:50000/irj/portal

We are facing some problems accessing the webdynpro & transaction iViews through internet via https.

So, We want to use the <b>Dynamic System Resolution</b> (http://help.sap.com/saphelp_nw04/helpdata/en/21/dfd241cb76c417e10000000a155106/frameset.htm) for this.

The idea is to make the resolution of the system dynamic. That means we define two system objects (one for remote and one for local) aliased "SystemXYZ_intranet" and "SystemXYZ_extranet". During the computation of a webdynpro URL the AppIntegrator will resolve the value of the parameter "System". The iView will contain the value "SystemXYZ". If thecustomer is outside the intranet, it will return "SystemXYZ_extranet".

I need to create a system resolving service based on whether the user is an intranet user or internet user??

How to distinguish whether the logged on user is an internet user or intranet user?

Can any1 help me on the same.

Awaiting your inputs.

Cheers,

SK,

You can do this by developing a Custom Login Module that uses the UME API to move the user into a user group for Internet users or Intranet users, which the DSR service can access via the IUser object passed to the DSR through the parameter of:

public String getAlternativeSystem(IUser user, String alias)

using

user.getParentGroups(true);

and iterating through the groups until you match the groupname or id to the one you moved the user into in the login module.

Seems to work fine for us.

hi steve,

Thanks for the reply.

But, even to move the user into a userGroup i need to distinguish b/w an internet and an intranet user right ??

How do i do that? any sample code for that ?? plz share it with me..

Hi,

I have also looked in the weblog: https://weblogs.sdn.sap.com/pub/wlg/1432

We have different portal-systems to get data as transaction iViews (from ECC system) and

webdynpro iViews (from EP system).

I have created 2 additional systems in portal with alias names system1_intranet and

system2_internet for this DSR thing.

system1 properties:

WAS hostname: sapmachine2.domain.net:50000

WAS protocol: http

system2 properties:

WAS hostname: name.company.com:8443

WAS protocol: https

P.S.:: 8443 is the https port and 80 is the http port of the SAP webdispatcher

No user is an anonymous user. All users are assigned to a concerned roles (ess_role, manager_role etc..)

Consider a user with portal user-id 12345 (say). He can login both from intranet and internet with the same user-id. (i.e. we don't have any groups created to distinguish intranet and internet/extranet users)

I am not able to figure out the following:

internet user : how to figure out that 12345 is logging in from internet and route it to system2_internet through this DSR service.

intranet user: how to figure out that 12345 is logging in from intranet and route it to system1_intranet through this DSR service.

An internet user will access the portal using the URL https://sap1.name1.ae:8443/irj/portal and intranet user will access the portal using URL http://sapportal.domainname.net:50000/irj/portal

<b>In mappingService class --> checkUser() method --> I am not able to figure out how to know whether the user is from internet or intranet when i only have 'IUser' object

There should be some way to capture this current URL of the browser using Java in my service??? so that i can know whether the logged in user is an internet or intranet user ?? right ??</b>

Please find below my code.
