c# - Authentication with Active Directory by multiple clients -

-

a client work have existing active directory employee information, want create application can log in using information stored in active directory. application should have web (.net), mobile (android , iphone), , optional desktop interface.

i haven't worked active directory before. did study on active directory, , here's understand far:

there 2 ways authenticate active directory:

  • by ldap : .net, can use system.directoryservices (and
    system.directoryservices.accountmanagement) namespace classes to
    perform authentication. android, iphone, guess have some
    libraries in platform ldap query active directory (any suggestion?)
  • by adfs identity provider: understand, adfs extension ad provides sso feature, , can configured identity provider, correct? , .net, android, iphone clients can use libraries oauth/openid authentication active directory through adfs

is understanding above correct? , way better? why should 1 use 1 not other? how azure ad come picture?

basically yes.

adfs 3.0 supports oauth2 - earlier versions don't.

note there number of identity providers can use ad e.g. shibboleth , pingfederate.

if want sso , if .net application claims based (i.e. wif) use adfs. outsource authentication trusted , verified security system , signed token contains whatever ad attributes require. adfs provides ability federate other sts e.g. azure ad.

in terms of mobile, have @ azure ad authentication library .net.

with ad have yourself. it's ad attributes. , need think how ensure security.

with adfs, can synch users aad , hence use on-premise credentials in cloud.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
