dartlang and dartdap library and connection to active directory - ldap

Question

I was looking for a good ldap library for Dart for connecting Microsoft Active Directory. I found dartdap, but I can't seem to get it working. I'm 100% shure that my CN and password is correct, because I can connect to Active directory for example with lpap browser.
The error I get is:
Uncaught Error: Invalid Credentials (49) msg=80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1
The ldap.yaml looks like this (address, password and username scrambled off course)
# LDAP configuration file
# default is used if no connection name is specified
default:
port: 389
host: xxx.xx.com
bindDN: cn=testaccount
password: xxxxxxxx
And the ldaptest.dart looks like this:
void readDataFromLDAPServer() {
var ldapConfig = new LDAPConfiguration("ldap.yaml","default");
var attrs = ["dn", "cn", "objectClass"];
var filter = Filter.substring("cn=A*");
var notFilter = Filter.not(filter);
ldapConfig.getConnection().then( (LDAPConnection ldap) {
ldap.search("dc=example,dc=com", filter, attrs).
listen( (SearchEntry entry) => print('Found $entry'));
// we expect to find non A entries
ldap.search("dc=example,dc=com", notFilter, attrs)
.listen( (SearchEntry entry) {
//print("Not search = ${entry}");
// todo: test entries.
});
});
}
Any idea, what might be wrong?

Answer 1

I am using the code below to successfully bind to a Microsoft AD server:
var host = "ip_address";
var ssl = false;
var port = null;
var bindDN = "accountname#domain.name";
var password = "password";
var connection = new LdapConnection(host: host);
connection.setProtocol(ssl, port);
connection.setAuthentication(bindDN, password);
Please note that my binding code differs from what you are using. I am also using an_ldap client for Dart 2.
