The (&(objectClass=user)(|(displayName)) search filter is invalid

Error:Internal : Could not execute code stage because exception thrown by code stage: The (&(objectClass=user)(|(displayName)) search filter is invalid.

emailAddress = "";
displayName = "Smith";

DirectorySearcher oSearch = new DirectorySearcher();
//oSearch.Filter = "name=" + displayName;
//oSearch.Filter = "(&(objectClass=user)(|(sAMAccountName = displayName))";
oSearch.Filter = "(&(objectClass=user)(|(displayName))";
SearchResult oResult = oSearch.FindOne();
DirectoryEntry oEntry = oResult.GetDirectoryEntry();

emailAddress = oEntry.Properties["emailAddress"].Value.ToString();

Trying to get email address based on display name.

Tried these as well. 

(&(objectClass=user)(&(displayName = {Smith})) 


oSearch.Filter = string.Format("(&(objectClass=user)(&(displayName = {Smith})))", displayName);

Thanks!

The search filter is invalid/incorrect since you're incorrectly using the OR(|) operator.

Though there is no condition given in the question, I'll assume a case that you're trying to find the email-address of the user whose display name is "Smith".

In this case, your filter would be:

oSearch.Filter = "(&(objectClass=user)(displayName=Smith))";
  // check the placement of brackets and the operator carefully as shown above.
  // if you need to search for names starting with "Smith", use wildcard: (displayName=Smith*)
SearchResult oResult = oSearch.FindOne();

if (null != oResult) // check for null values everywhere in your code to avoid NPE
DirectoryEntry oEntry = oResult.GetDirectoryEntry();

if (null != oEntry) // check for null values, else NP exception will be thrown
emailAddress = oEntry.Properties["emailAddress"].Value.ToString();

Please refer the TechNet article Active Directory: LDAP Syntax Filters for more information.
