LDAP querys: should use webservice or not?

Question

User-2087708997 posted

Hi Folks,

As a starter, let me describe the scenario:
There is this intranet app. (asp.net v1.1) which has many web contros. Each one of these web controls have a textbox, a label and a button. You place a name on the textbox, press the button and after the postback you get information for that name retrieved from Active Directory. This app. is used by about 500 users.

I have 2 clear ways to achieve the webcontrols to do that:
1- querying Active Directory directly from the web controls code.
2- consuming a web service which queryes Active Directory.

So, my question is: which one of these two options should I use? Not in terms of simplicity, but in terms of performance and best practices.

Thank you for your help!!!

 Are you able to cache the results in a SQL Server table? That way (provided you can accept a time lag in updating the cache) you could just update the cache overnight.

Without SQL Server caching you could use a web service approach if:

• You are prepared to use threading.
• You have something else useful to do while the data is fetched.
