I do have olcSaslRealm and olcAuthzregexp setup in my cn=config. I do not have saslauthd.conf setup. I ran kinit from my ldap server then tried to do an ldapsearch and it looks like syslog is providing the same information.

In my kdc log I don't see anything related to the ldapsearch I'm trying to perform. It did mention that it there was no host service ticket for my test server so I added one, but the test I just ran was directly on my ldap server. I do see this, I'm not sure if it is related to this problem:

Thanks, Josh

Check your syslog - auth facility, and check your kdc logs.
a couple of things that may need attention. you need to map the kerberos-established identities to ldap user objects. adjust the below to match your environment (these need to be in cn=config):
olcSaslRealm: BPK2.COM
This may be necessary.
olcAuthzRegexp: {0}uid=([^,]*),cn=bpk2.com,cn=gssapi,cn=auth uid= $1,ou=Users,dc=bpk2,dc=com olcAuthzRegexp: {1}uid=([^,]*),cn=gssapi,cn=auth uid= $1,ou=Users,dc=bpk2,dc=com
This is not necessary, for GSSAPI authentication. That is, the error message above is a SASL error message. olcAuthzRegexp would be needed to map the user after authentication has been completed.
you might also need to tell sasl to use the kerberos auth mechanism, and where to find the ldap servers. again, adjust to your environment (saslauthd.conf):
ldap_servers: ldap://ldap1.bpk2.com/ ldap://ldap2.bpk2.com ldap_use_sasl: yes ldap_mech: kerberos5 ldap_auth_method: fastbind keytab: /etc/ldap.keytab
This is also not necessary, as GSSAPI authentication does not depend on or use saslauthd. It would be needed if performing pass-through or PLAIN/LOGIN authentication.
