hi 
i'm trying to enable ldap authentication both on ssh and console but apparently busybox and the initrd configuration is preventing this from working. tried encrypting the password as SHA and SSHA to no avail in JXplorer. it looks like its not even authenticating against ldap tried both local and ssh ( openssh dosen't even suport pam aparently in this build) 
i tried this from the openldap server  as well as another node on the network same issue (with older tinycore ... 6.3 x64 as well)
here is a few config files 
/etc/nsswitch.conf: 
passwd:     files ldap
group:      files ldap
shadow:     files ldap
hosts:      files dns
networks:   files
rpc:        files
services:   files
/usr/local/ldap.conf
BASE    dc=ericsolutions, dc=info
scope sub
suffix          "dc=mydomain,dc=info"
## when you want to change user's password by root 
rootbinddn cn=admin,dc=mydomain,dc=info
## *** replaced my real domain name with mydomain above ***
## there are needed when your ldap dies
timelimit 5
bind_timelimit 5
uri ldap://10.0.1.4/
pam_password <stripped this but i tried plain text no info on this> 
ldap_version 3
pam_filter objectclass=posixAccount
pam_login_attribute uid
pam_member_attribute memberuid
nss_base_passwd ou=Computers,dc=cognifide,dc=pl
nss_base_passwd ou=People,dc=cognifide,dc=pl
nss_base_shadow ou=People,dc=cognifide,dc=pl
nss_base_group  ou=Group,dc=cognifide,dc=pl
nss_base_hosts  ou=Hosts,dc=cognifide,dc=pl
