1) Password must be ldap password fir ldzp user : try and connect through other mean
2) filter must retrieve the ldap user : try and search user with given username
3) log seems to show that you enter "username" to log in ProjeQtOr : does this user exist in ldap with corresponding uid ?
4) You do not need to import ldap user in Projeqtor : this is the interest of ldap connectivity, authentication is devoted to ldap, with ldap password
5) you define in global parameters default profile for new users
6) Yes, projeqtor automatically creates a projeqtor user on first ldap connection, retrievong the cn (common name) and email

Having very similar problems with LDAP connection, any assistance would be greatly appreciated.
We keep getting the error: ldap_bind(): Unable to bind to server: Invalid credentials

1. The user we are trying to log in with is a valid working LDAP user, "ourdomain.netbmullins", with valid email address, and can log in via other means.
2. The LDAP authentication user has also been verified and can log in via other means.
3. We use Active Directory, so presumably the default user filter specified in Projeqtor works; I am unsure how to test.
4. LDAP authentication module in PHP.ini is enabled (that was the first problem I ran into).
5. There are no firewalls blocking the LDAP port, and we have not changed the default port number.

Parameters are:
Connection with LDAP Users: YES
LDAP base dn : DC=ourdomain,DC=net
LDAP host: dc1.ourdomain.net
LDAP port: 389
LDAP version: 3
LDAP user: CN=ldapprojeqtor,DC=ourdomain,DC=net
LDAP Passwowrd: ****** (our password)
LDAP user filter: uid=%username%

==============

Solved my own problem.

1. On our Microsoft Server 2012 R2 setup, neither the filter 'uid=' nor the filter 'sAMaccountName=' worked for me. Instead I had to use the filter 'userPrincipalName=%USERNAME%', specifying the login as 'username @ ourdomain.net' (without spaces, of course)
2. I did not specify the 'LDAP user' connection string correctly.

As suggested in other threads, if you are using Active Directory, use the command line tool "dsquery" to get the exact LDAP user connection string, like this:

or

The exact connection string that finally solved my problem was:

where CN=firstname lastname
NOT CN=username

One other rookie mistake I made (and I should know better) - when testing, close out your browser completely OR clear the cache settings before each attempt.
