Hello,
I've been having a hard time the past 9 days trying to debug an issue with the people picker.
I've deployed an environment with 5 farms the configuration is as follows.
Farm 1: 3WFE + 2 APP
Farm 2: 2WFE + 2 APP
Farm 3: 2WFE + 2App
Farm 4: 2WFE/APP
My issue is that i have configured people picker searchadforest property for all of them properly.And also created a one way trust.
The people picker works on the front ends, for the normal web application of my websites and also for the central administration if i provision it on the front ends but it refuses to work on the app servers. Even if i provision the Microsoft web site service so that it acts as a front-end for the website it still does not work for the same site that works on the WFE.
I have don netmon on the servers and it seems for some reason the app servers don't send the LDAP SearchRequest message. I've also traced the people picker search procedure and it seems it builds and sends the same query on both working and not working but then gets only one result from the local domain.
Everywhere i read the multiple domain settings it always mentions the the WFE does the query-ing which is true but how can i make the app servers do it as well. How does SharePoint decide which one is a app and witch one is a WFE.
How does SharePoint prevent the app server from doing the request i want to activate the LDAP search capability on the app servers as well.
Any help would be greatly appreciated.
