1) Hv u checked dir perms for /etc and /etc/openldap?
ls -ld /etc; ls -ld /etc/openldap
2) I assume u hv run authconfig, if so, edit /etc/pam.d/system-auth
change this:
account required /lib/security/$ISA/pam_unix.so
to that:
account sufficient /lib/security/$ISA/pam_unix.so
3) if 1) and 2) do not help
Can u post these files on ldap client (full content pls) to us (or to just me as too much info):
/etc/ldap.conf,
/etc/openldap/ldap.conf
/etc/pam.d/system-auth
/etc/nsswitch.conf
/etc/resolv.conf
/etc/hosts
and these files on ldap server:
slapd.conf
output of:
partial ldapsearch output showing the testuser user details
rpm -qa | grep openldap
rpm -qa | grep nss_ldap
rpm -qa | grep pam
strace id testuser (u must hv strace rpm installed)
ldd `which id`

getent passwd as root and as testuser both display exactly the /etc/passwd
file on the client machine
* as root on the client i can see that /etc/openldap/cacert.pem is world

this looks as if i have a problem with the permission of
/etc/openldap/cacert.pem, but what can i do?

I did this with different levels from -1 to 2048 but could never see
anything apropriate to the TLS connection... which level should i use and
what exprssion sould i look 4.

Compiling is at the moment to freaky for me. Everytime i compile a software
and it doesn't run straight trough i can never solve the issue... So i use
the binarys supported by Fedora Core 2. But i tried a hind form Vsevolod. Is
this maybe what you mean? (see next point)

doing this and then issuing
# id testuser
gives me
