[英]Find username from Active Directory using email id
I am finding user name from Active Directory by passing email id.我通过传递电子邮件 ID 从 Active Directory 中查找用户名。 It is working fine.
它工作正常。 But it takes 30-40 seconds to get the username.
但是获取用户名需要 30-40 秒。 Is there any other better way to find the username from Active Directory by email address?
还有其他更好的方法可以通过电子邮件地址从 Active Directory 中查找用户名吗?
Please refer to my code:请参考我的代码:
using (PrincipalContext context = new PrincipalContext(ContextType.Domain, "domainname"))
{
UserPrincipal userPrincipal = new UserPrincipal(context);
PrincipalSearcher principalSearch = new PrincipalSearcher(userPrincipal);
foreach (UserPrincipal result in principalSearch.FindAll())
{
if (result != null && result.EmailAddress != null && result.EmailAddress.Equals(user.Email, StringComparison.OrdinalIgnoreCase))
{
user.FirstName = result.GivenName;
user.LastName = result.Surname;
}
}
}
You don't need to enumerate all users to to find one of them!您无需枚举所有用户即可找到其中之一! Try this code:
试试这个代码:
using (PrincipalContext context = new PrincipalContext(ContextType.Domain, "domainname"))
{
UserPrincipal yourUser = UserPrincipal.FindByIdentity(context, EmailAddress);
if (yourUser != null)
{
user.FirstName = yourUser.GivenName;
user.LastName = yourUser.Surname;
}
}
If that shouldn't work, or if you need to search for several criteria at once, used the PrincipalSearcher
with the QBE (query-by-example) approach - search the one user you need - don't cycle through all users!如果这不起作用,或者如果您需要一次搜索多个条件,请将
PrincipalSearcher
与 QBE(按示例查询)方法一起使用 -搜索您需要的一个用户 - 不要在所有用户之间循环!
// create your domain context
using (PrincipalContext context = new PrincipalContext(ContextType.Domain, "domainname"))
{
// define a "query-by-example" principal -
UserPrincipal qbeUser = new UserPrincipal(ctx);
qbeUser.EmailAddress = yourEmailAddress;
// create your principal searcher passing in the QBE principal
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);
// find all matches
foreach(var found in srch.FindAll())
{
// do whatever here - "found" is of type "Principal" - it could be user, group, computer.....
}
}
using System.DirectoryServices.AccountManagement;
// Lock user
using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
UserPrincipal yourUser = UserPrincipal.FindByIdentity(context, logonName);
if (yourUser != null)
{
if(!yourUser.IsAccountLockedOut())
{
yourUser.Enabled = False;
yourUser.Save();
}
}
}
