Hello. I am using powershell and DirectoryServices.DirectorySearcher ldap code to query a non-AD LDAP server. I can retrieve all attributes except operational attributes such as createtimestamp and modifytimestamp.
Interestingly, if I switch to using the LDAPConnection class in the Protocols namespace, and specify “+” in the attribute list, I can retrieve operational attributes, but not any other attributes.
Does anyone have suggestions on how I can retrieve these attributes?
