    Hi,

    I'm in trouble with my linux box (kernel 2.4.21-4.EL) on which I use remote Ldap
    authentication : When I logging in with a user ID registered in the LDAP
    directory, I got the following message before getting a shell prompt : "Cannot
    find name for user ID 780".
    I'm well authenticated but it seems that the user ID cannot be retrieved in the
    LDAP tree...
    The "id" command on the machine says :
    "uid=780 gid=100(users) groups=100(users)"
    I have configured the system to use pam_ldap (in /etc/pam.d/system-auth) and I
    have also configured the nss_ldap (in /etc/nsswitch.conf).
    If I create a file system entry in my home directory, the system does not match
    my user ID as well :
    [ users]# touch foo
    [ users]# ll foo
    -rw-rw---- 1 780 users 0 May 28 15:20 foo

    But, if I become root, I retrieve the user ID correctly as shown hereafter:
    [ users]# su
    Password:
    [ users]# id
    uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),6(disk),10(wheel)
    [ users]# ll foo
    -rw-rw---- 1 user1 users 0 May 28 15:20 foo

    Does anybody have an idee to help me on this problem?

    I use the following ldap packages on my client box:
    openldap-2.0.27-11
    nss_ldap-207-2
    openldap-clients-2.0.27-11
    And I use the openldap-servers-2.0.27-11 package on the LDAP server.

    Thanks in advance.
    Regards.
