Hello i have nginx 1.16.0 and some modules: nginx-auth-ldap, nginx-dav-ext-module, headers-more-nginx-module, nginx-upload-module.

I try do ldap auth on some directory.

config

http {

####Block_integration_with_ldap ##############
ldap_server mydomain{
url "ldap://mydomain:3268/DC=mydimain,DC=local?sAMAccountName?sub?(objectClass=person)";
binddn 'admin@mydomain.local';
binddn_passwd 'adm_pass';
require valid_user;
}
ldap_server mydomain2{
url "ldap://mydomain:3268/DC=mydimain,DC=local?sAMAccountName?sub?(objectClass=person)";
require user "CN=test,DC=MYDOMAIN,DC=LOCAL";
group_attribute uniquemember;
group_attribute_is_dn on;
referral on;
}

}


With first auth "mydomain" on location / all Ok.
But With second auth "mydomain2" on location /user ask login and password but not work

Log:
http_auth_ldap: Initial bind failed (49: Invalid credentials [80090308: LdapErr: DSID-0C090400, comment: AcceptSecurityContext error, data 52e, v1db1])

49: Invalid credentials talk about incorrect password. But i sure what password is correct.

Has anyone had such problems?
