SASL working but kerberos DOMAIN is not set

[Friedrich Locke <friedrich.locke@gmail.com>]

I have setted openldap+sasl+kerberos.
It is working but the keberos realm is not seted in the bind dn, why?

Here is my session:

sioux@gustav$ ldapsearch -Y GSSAPI -b "" -s base -LLL supportedSASLMechanisms
SASL/GSSAPI authentication started
SASL username: sioux@UFV.BR
SASL SSF: 56
SASL data security layer installed.
dn:
supportedSASLMechanisms: OTP
supportedSASLMechanisms: NTLM
supportedSASLMechanisms: GSSAPI
supportedSASLMechanisms: DIGEST-MD5
supportedSASLMechanisms: CRAM-MD5

sioux@gustav$

Here is what i got from slapd err output :

...

do_bind: dn () SASL mech GSSAPI
slap_sasl_getdn: u:id converted to uid=sioux,cn=GSSAPI,cn=auth

Any ideia about what is going on ?
