Hi folks,
I'm having a real hard time debugging this, and the moment I think it's a
Kerberos config problem, and not really LDAP.
I'm trying to do a new ldap+MIT kerberos install , on a new Fedora 7 box. I
can kinit, but I can't get ldapsearch or ldapwhoami to work locally. I
thought it was a read problem with the keytab files, but I tried setting
KRB5_KTNAME to a keytab file I knew ware readable by slapd, and that did not
help. I also checked permissions on my certificates, and that seems OK too.
ldapsearch -x does work, but ldapsearch -Y GSSAPI does not.

I tried running strace on ldapwhoami, slapd and krb5kdc, but strace does not
show which resource is not accessible, or even any attempts to open the
keytabs or anything in /etc/openldap/cacerts. I'm surprised that the strace
on krb5kdc never shows any responce to my ldap queries.

I tried making briefly making /etc/krb5.keytab world readable, it did not
change the "No such file" error.
The logs I check are /var/log/messages, slapd and krb5kdc.log. The logs do
not show the ldap client error. I DID see some SELINUX errors for
krb5kdc_rcache and krb5.conf, but I ran restorecon and fixed those. This did
not stop the error. I guess I'll try turning SELINUX off, and see if that
makes any difference.

Any help would be greatly appreciated
