I have a fedora client that is authenticating to a centos server running 389 ds and kerberos
I can run kinit <my-user-principal>
on the fedora client successfully and get a ticket, but no matter what I try I just cannot authenticate with kerberos to the 389 server.
whenever I try ldapwhoami -I -Y GSSAPI
I get the following error:
SASL/GSSAPI authentication started
SASL Interaction
Please enter your authorization name: test@LAB2.LOCAL
ldap_sasl_interactive_bind_s: Invalid credentials (49)
additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Unknown error)
Doing a klist I can see I have my tickets:
Ticket cache: FILE:/tmp/krb5cc_0

I edited the nsslapd-accesslog-level attribute of cn=config to be 260 and when I checked the access log I found this (172.16.86.200 is the IP of my fedora client):
tail -n 15 /var/log/dirsrv/slapd-dp100srv1/access

What is BIND dn="" about? That can't be right, but according to the 389 docs the default sasl maps that are already configured should be enough for my purposes.
Where else can I look to troubleshoot this?
