I have no idea why it is returning Permission denied.
Is it reproducible when you run this?

$ ldapsearch -Y GSSAPI -H /var/run/slapd-EXAMPLE.COM.socket

We need to find out why it is blowing up on GSSAPI negotiation.
Wild guess is that /etc/dirsrv/ds.keytab could have wrong

# ls -lZ /etc/dirsrv/ds.keytab

If you manage to reproduce it, you can attach strace to the running

Perhaps this one:
[pid 13449] open("/etc/krb5.keytab", O_RDONLY) = -1 EACCES (Permission denied)
# ls -lZ /etc/krb5.keytab
-rw-------. root root system_u:object_r:krb5_keytab_t:s0 /etc/krb5.keytab
But looking into the backup of this system, even a week and a month
ago, that file had the same permissions/ownership. And changing it to
644 temporarily doesn't fix the "ldap_sasl_interactive_bind_s: Invalid
credentials (49)" from ldapsearch.
DS should use /etc/sysconfig/dirsrv to set its KRB5_KTNAME env variable
to /etc/dirsrv/ds.keytab. I guess that it cannot get this info from the
file, thus it falls back to Kerberos library default which is
/etc/krb5.keytab. That obviosuly fails because it is accesible only to
root and contains keys only to host/, nfs/, and cifs/ (if you have
