Hello,

I struggle with an Debian GNU/Linux (Lenny) and

* slapd 2.4.11-1 * heimdal-kdc 1.2.dfsg.1-2.1 * libsasl2-modules-gssapi-heimdal 2.1.22.dfsg1-23

With this configuration:

/etc/ldap/slapd.conf: # Kerberos Configuration sasl-host kerberos.lab.swapon.de sasl-realm LAB.SWAPON.DE

# Mapping Kerberos Authentication Identities authz-regexp uid=([^,]*),cn=lab.swapon.de,cn=gssapi,cn=auth ldap:///ou=people,dc=lab,dc=swapon,dc=de??one?(&(uid=$1)(objectClass=person))

/etc/ldap/sasl2/slapd.conf: mech_list: GSSAPI log_level: 7

Then I get a kerberos ticket and start ldapsaerch:

$ ldapsearch -H ldaps://ldap.lab.swapon.de/ SASL/GSSAPI authentication started ldap_sasl_interactive_bind_s: Other (e.g., implementation specific) error (80)

The slapd logfile isn't very helpfull:

slapd[11480]: conn=2 fd=14 ACCEPT from IP=[2001:6f8:12ec:11::389:fefe]:60487 (IP=[2001:6f8:12ec:11::389:fefe]:636) slapd[11480]: conn=2 fd=14 TLS established tls_ssf=128 ssf=128 slapd[11480]: conn=2 op=0 SRCH base="" scope=0 deref=0 filter="(objectClass=*)" slapd[11480]: conn=2 op=0 SRCH attr=supportedSASLMechanisms slapd[11480]: conn=2 op=0 SEARCH RESULT tag=101 err=0 nentries=1 text= slapd[11480]: conn=2 op=1 BIND dn="" method=163 slapd[11480]: SASL [conn=2] Failure: GSSAPI Error: No credentials were supplied, or the credentials were unavailable or inaccessible.

(unknown mech-code 0 for mech unknown) slapd[11480]: conn=2 fd=14 closed (connection lost)

The KDCs logfile is more interesting:

It's clear that this TGS-REQ is failing: the realm "LAB" in the principal "krbtgt/LAB@LAB.SWAPON.DE" doesn't exist. Correct would be: "krbtgt/LAB.SWAPON.DE@LAB.SWAPON.DE".

At present I have no clue how to fix this. Good ideas would be appreciated.
