SASL AuthN to LDAP

18 Oct 2016


      i am trying to use a Kerberos keytab file to authenticate to LDAP.  the 
keytab file is the same one used to authenticate users against the 
Kerberos database.  the principal in the keytab has been mapped to an 
object in LDAP, for access to be granted.  i dont seem to be getting the 
configs correct for the LDAP binds to work.  can you shed light on what 
i am missing?

i am setting

KRB5_CLIENT_KTNAME = '/etc/raddb/radius.keytab'

in the sasl {} stanzas in mods-available/ldap, which is linked to 
mods-enabled/.  the radiusd -X output below indicates that anonymous 
binds are being attempted.  this seems to indicate the keytab is not 
being picked up and the identity is not being found.  i can run a 'kinit 
-kt /etc/raddb/radius.keytab' and get a TGT back.  i can also run 
'ldapwhoami' with that TGT and get the mapped LDAP identity back.  am i 
going about setting the KRB5_CLIENT_KTNAME wrong?
