I'm trying to deploy Ubuntu 12.04 via xCAT, everything works except the automatic configuration of LDAP, the preseed file is read but the file /etc/nsswitch is not written properly.

My Preseed File:

[...]
### LDAP Setup
nslcd nslcd/ldap-bindpw password
ldap-auth-config ldap-auth-config/bindpw password
ldap-auth-config ldap-auth-config/rootbindpw password
ldap-auth-config ldap-auth-config/binddn string cn=proxyuser,dc=example,dc=net
libpam-runtime libpam-runtime/profiles multiselect unix, ldap, gnome-keyring, consolekit, capability
ldap-auth-config ldap-auth-config/dbrootlogin boolean false
ldap-auth-config ldap-auth-config/rootbinddn string cn=manager,dc=xcat-domain,dc=com
nslcd nslcd/ldap-starttls boolean false
nslcd nslcd/ldap-base string dc=xcat-domain,dc=com
ldap-auth-config ldap-auth-config/pam_password select md5
ldap-auth-config ldap-auth-config/move-to-debconf boolean true
ldap-auth-config ldap-auth-config/ldapns/ldap-server string ldap://192.168.32.42
ldap-auth-config ldap-auth-config/ldapns/base-dn string dc=xcat-domain,dc=com
ldap-auth-config ldap-auth-config/override boolean true

libnss-ldapd libnss-ldapd/clean_nsswitch boolean false
libnss-ldapd libnss-ldapd/nsswitch multiselect passwd,group,shadow
nslcd nslcd/ldap-reqcert select
ldap-auth-config ldap-auth-config/ldapns/ldap_version select 3
ldap-auth-config ldap-auth-config/dblogin boolean false

nslcd nslcd/ldap-uris string ldap://192.168.32.42
nslcd nslcd/ldap-binddn string

[...]

After the installation, nsswitch.conf rimains unchanged.

Has someone an idea??

Thanks!
