Description Simo Sorce 2008-12-18 16:29:25 UTC
Currently in /etc/sysconfig/dirsrv we suggest to put the keytab in an instance like this:
# In order to use SASL/GSSAPI the directory
# server needs to know where to find its keytab
# file - uncomment the following line and set
# the path and filename appropriately
# KRB5_KTNAME=/etc/dirsrv/slapd-instance/keytab ; export KRB5_KTNAME

A per instance keytab does not make much sense for servers.
Kerberos clients use the machine FQDN to obtain a ticket like ldap/FQDN, there is nothing that can amke a lcient understand how to get a per-instance ticket.
Therefore by default a keytab should be considered a per server option.

Also the file /etc/sysconfig/dirsrv is sourced for all instances, so again all instances would ultimately get the same keytab.

Finally a keytab is normally named either krb5.keytab or <service>.keytab

I suggest the default be changed to:
# KRB5_KTNAME=/etc/dirsrv/ds.keytab ; export KRB5_KTNAME

This is the same default we used in IPA since the beginning and fits the above description.

Comment 1 Rich Megginson 2009-02-16 22:54:53 UTC
Done.
Checking in initconfig.in;
/cvs/dirsec/ldapserver/ldap/admin/src/initconfig.in,v  <--  initconfig.in
new revision: 1.4; previous revision: 1.3
done

Comment 2 Jenny Severance 2009-04-01 18:48:46 UTC
How can we verify this?  I have seen default GSSAPI error messages looking for keytab  - /etc/krb5.keytab  but not /etc/dirsrv/ds.keytab.

Comment 3 Rich Megginson 2009-04-01 19:13:37 UTC
It's just the commented out assignment - just check to see that the commented out assignment in /etc/sysconfig/dirsrv is correct

by default, sasl/gssapi will look for /etc/krb5.keytab if KRB5_KTFILE is not defined.

Comment 4 Jenny Severance 2009-04-01 19:24:11 UTC
fix verified DS 8.1 RHEL 4

/etc/sysconfig/dirsrv:

# In order to use SASL/GSSAPI (Kerberos) the directory
# server needs to know where to find its keytab
# file - uncomment the following line and set
# the path and filename appropriately
# KRB5_KTNAME=/etc/dirsrv/myname.keytab ; export KRB5_KTNAME
