After some time, the user's name is lost in the shell (Working with LDAP)

Binary package hint: nscd

LDAPS works great in my LAN, except an error of "Not Inititialize HALT". LDAP works with authentication on server and clients (TLS/SSL).
The problem is in the client. After some hours from the boot (well, from the starting of nscd), the system can authenticate users but the system can't see them. In other terms:
- Recently booted:
darkxer0x@client:~$getent passwd |grep darkxer0x
[THE SYSTEM ANSWERS] darkxer0x:x:1000:1000:HOM,,,:/home/darkxer0x:/bin/bash

- After some hours:
I have no name!@client:~$getent passwd |grep darkxer0x
[THE SYSTEM ANSWERS]
(I have run wireshark, and there are encrypted communications between client and server)

- Now, I run /etc/init.d/nscd restart
darkxer0x@client:~$getent passwd |grep darkxer0x
[THE SYSTEM ANSWERS] darkxer0x:x:1000:1000:HOME,,,:/home/darkxer0x:/bin/bash

I'll attach /etc/nscd.conf, /etc/nsswitch.conf, /etc/ldap.conf,/etc/ldap/ldap.conf, /etc/pam.d/common-*

If other output commands are needed, just tell me
