[reza]

Hallo allezusammen,

ich habe ein Problem mit der Authentification über ldap,sasl und pam.

etc/ldap.conf
uri ldaps://ldap.mydomain.de/
ldap_version 3
host 192.168.0.1
base dc=mydomain,dc=de
scope sub
pam_login_attribute uid
pam_filter objectclass=posixAccount
nss_base_passwd ou=People,dc=mydomain,dc=de?one
nss_base_shadow ou=People,dc=mydomain,dc=de?one
nss_base_group ou=Group,dc=mydomain,dc=de?one
sslno

/etc/nsswitch.conf
passwd: ldap files
shadow: ldap files
group: ldap files

/etc/pam.d/login
auth required pam_securetty.so
auth required pam_nologin.so
auth sufficient pam_ldap.so
auth required pam_unix2.so nullok try_first_pass
#set_secrpc
account sufficient pam_ldap.so
account required pam_unix2.so
password required pam_pwcheck.so nullok
password required pam_ldap.so use_first_pass use_authok
password required pam_unix2.so nullok use_first_pass
use_authtok
session required pam_unix2.so none # debug or trace
session required pam_limits.so
session required pam_env.so
session optional pam_mail.so

Beim anmelden bekomme ich folgende fehlermeldung:
/var/log/messseges

Kann mir eventuel jemand weiterhelfen, was ich falsch mache?

Danke im vorraus.
