"i have no name" libnss-ldap

Thanks Jeruvy, that solved my question.

But anyhow, when i login as LDAP user i cannot change password with passwd, nor with ldappasswd. ldappasswd gives error ldap_bind: Invalid credentials

I would hazard to guess this is inconsistent with your setup. I found this link about it, perhaps it will help. If not post back your configs.

Yeah, red that already. Double-checked my config, and don`t found anything suspicious.

Thats how it looks:

dn: olcDatabase={-1}frontend,cn=config
objectClass: olcDatabaseConfig
objectClass: olcFrontendConfig
olcDatabase: {-1}frontend
olcAccess: {0}to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage by dn="cn=admin,dc=totan,dc=ru" write by * read

dn: olcDatabase={1}hdb,cn=config

and, naturaly

root@alpha:/home/oljas# cat /etc/nsswitch.conf
passwd: files ldap
group: files ldap
shadow: files ldap

I use Apache Directory Studio to edit LDAP entries and cn=config. I connects with and without SSL/TLS, anonymous or by cn=admin,dc=totan,dc=ru.

Is there any other logs/config files a have to look for?

and the
ldapadduser test
works, but dont create password for the user

ldappasswd test
SASL/DIGEST-MD5 authentication started
Please enter your password:
ldap_sasl_interactive_bind_s: Invalid credentials (49)
 additional info: SASL(-13): user not found: no secret in database

Maybe I have misconfiguration of olcAccess, because i have no clue what is the password the ldappasswd asks for.
