sql server - SQL Query to loop through AD OUs and get a count of objects -


i'm trying produce report has count of computer objects within many, many ad ous sql server can join other data in sql db , create report ssrs.

i've figured out how single ou (which represents physical site location unique code in situation) need able ous in directory.

this query result 1 single ou. ideas?

            declare @sitecode int             set @sitecode = 1234              declare @region nvarchar(100)             set @region = (                             select top 1        regionname                                        tbl_adsiteinfo                                       sitecode = @sitecode                           )              declare @sitename nvarchar(250)             set @sitename = (                                     select top 1    sitename                                                tbl_adsiteinfo                                               sitecode = @sitecode                               )              declare @sql nvarchar(1000)             set @sql = '             select top 901  count(*) ''count''                        openquery(                                         adsi,                                         ''                                         select distinguishedname,extensionattribute3,extensionattribute4,extensionattribute2, name                                         ''''ldap://ou=computers,ou=' + @sitename + ',ou=' + @region + ',ou=branches,dc=company,dc=com''''                                         objectclass = ''''computer''''                                         ''                                     ) tbladsi              '              exec dbo.sp_executesql @sql

i figured out how myself after thinking while.

first, query existing table dataset of unique ids in org our sites (sitecode) , write them temp table column called 'processed' has value of 0.

then, while loop has condition of select count(sitecode) #tmp processed = 0 > 1

then select top 1 processed = '0' sitecode , use query table ldap path site's container, , ldap query count of computer objects , write value yet table hold results want. when i've got data need, set record processed = '1' , loop continues.

eventually, sites have processed = '1' , loop finish. drop temp table don't need anymore.

i'm bit concerned execution time blow out doing way apart hand counting, i'm not sure else do, , i'm pretty happy anyway :)

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
