Is there way to completly recreate LdapConnection (with native part included)?

[Kashemir78]

Hi.

This is my first time working with LDAP and I'm stuck with a problem - is it possible to reset the connection? Any attempt to re-create the LdapConnection and reconnect after binding results in a search error.

As far as I understand, the native instance is static and in fact is simply reused.

So I wrapped LdapConnection in a singleton and everything works fine, until at some point when the connection with the AD controller lost for example and any calls to the connection lead to an error.

LdapForNet.LdapOperationsErrorException: Operations error. 000004DC: LdapErr: DSID-0C090A5C, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v4563. Result: 1. Method: ldap_parse_result.

I did not find any way to completely recreate/restore the connection - to solve the problem I have to restart the container (docker/linux) and its not looks good :(

Code:

				// init once
                _connection = new LdapConnection();
                _connection.Connect("srv.com", 636, Native.LdapSchema.LDAPS);
                _connection.TrustAllCertificates();
				
				// repeatable

				await _connection.BindAsync(Native.LdapAuthType.Simple, new LdapCredential {
					username = "username",
					Password = "userpassword",
				})!;
				var entries = await _connection.SearchAsync("dc=srv,dc=com", $"(sAMAccountName={sAMAAccountName})", token: stoppingToken);
