英文:
.NET core 3.1 novell.directory.ldap doesn't get all LDAP users
问题
我正在开发一个基于.NET Core (3.1)的应用程序，它连接到Active Directory以获取用户信息。
我使用的是Novell.Directory.Ldap.NETStandard 3.6.0版本。
我有超过4000个用户，但我只得到了大约800个用户。
LDAP MaxPageSize是5000，当我尝试使用System.DirectoryServices时，我可以获取所有用户。
但我必须使用Novell，因为我需要将应用程序部署在docker上。
```lang-cs
var ldapConn = new LdapConnection { SecureSocketLayer = false };
ldapConn.Connect(domainName, 389);
ldapConn.Bind(username, password);
ILdapSearchResults lsc = ldapConn.Search("OU=myOU,DC=domain,DC=com",
LdapConnection.ScopeSub, "(objectClass=person)", null, false);
CSV WriteToCSV = new CSV();
while (lsc.HasMore())
{
nextEntry = lsc.Next();
LdapAttributeSet attributeSet = nextEntry.GetAttributeSet();
if (attributeSet.ContainsKey("sAMAccountName"))
{
string result = attributeSet.GetAttribute("sAMAccountName").StringValue;
WriteToCSV.WriteToCsv("Persons.csv",);
}
}
> 错误: 超过大小限制

我使用"SearchUsingSimplePaging"函数来解决这个问题
var ldapConn = new LdapConnection { SecureSocketLayer = false };
ldapConn.Connect(domainName, 389);
ldapConn.Bind(username, password);
SearchOptions options = new SearchOptions("OU=my_OU,DC=domain,DC=com", LdapConnection.ScopeSub, "(objectClass=person)", null);
var searchResult = ldapConn.SearchUsingSimplePaging(options, 1000);
CSV WriteToCSV = new CSV();
foreach (var ldapEntry in searchResult)
{
dapAttributeSet attributeSet = ldapEntry.GetAttributeSet();
if (attributeSet.ContainsKey("sAMAccountName"))
{
string result = attributeSet.GetAttribute("sAMAccountName").StringValue;
WriteToCSV.WriteToCsv("Persons.csv", result);
}
}
