passwd ldap request to ActiveDirectory fails on half of 2500 users
- by groovehunter
We just setup ActiveDirectory in my company and imported all linux users and groups.
On the linux client: (configured to ask ldap in nsswitch.conf):
If i do a common ldapsearch to the AD ldap server i get the complete number of about 2580 users.
But if i do this it only gets a part of all users, 1221 in number:
getent passwd | wc -l
Running it with strace shows kind of attempt to reconnect
My ideas were:
Does the linux authentication procedure run ldapsearch with a parameter incompatible to AD ldap ?
Or probably it is a encoding issue. The windows user are entered in AD with all kind of characters.
Maybe someone could shed light on this and give a hint how to debug that further!?
Here's our ldap.conf
host audc01.mycompany.de audc03.mycompany.de
base ou=location,dc=mycompany,dc=de
ldap_version 3
