Joerg, thank you very much for your input - most appreciated!

I simply installed heimdal with
pkg_add -r heimdal

I did not set HEIMDAL_HOME at any point.

"env" shows that HEIMDAL_HOME is not set.

So according to /usr/ports/security/cyrus-sasl2/Makefile I guess we 
would have CONFIGURE_ARGS+=--enable-gssapi but no --with-gss_impl=heimdal

To be on the safe side, I tried
cd /usr/ports/security/cyrus-sasl2/
make clean
export HEIMDAL_HOME=/usr
make

(during make I noticed a few cc ... -DKRB5_HEIMDAL ...)

ldapsarch still coredumps with gss_init_sec_context () from 
/usr/lib/libgssapi.so.10

I noticed that I have libgssapi's - no clue why:

srv02# ls /usr/lib/libgss*
/usr/lib/libgssapi.a /usr/lib/libgssapi_krb5.a 
/usr/lib/libgssapi_krb5_p.a /usr/lib/libgssapi_ntlm.so.10 
/usr/lib/libgssapi_spnego.a /usr/lib/libgssapi_spnego_p.a
/usr/lib/libgssapi.so /usr/lib/libgssapi_krb5.so 
/usr/lib/libgssapi_ntlm.a /usr/lib/libgssapi_ntlm_p.a 
/usr/lib/libgssapi_spnego.so
/usr/lib/libgssapi.so.10 /usr/lib/libgssapi_krb5.so.10 
/usr/lib/libgssapi_ntlm.so /usr/lib/libgssapi_p.a 
/usr/lib/libgssapi_spnego.so.10
srv02# ls /usr/local/lib/libgss*
/usr/local/lib/libgssapi.a /usr/local/lib/libgssapi.la 
/usr/local/lib/libgssapi.so /usr/local/lib/libgssapi.so.2

Next I tried pkg_delete heimdal-1.0.1_1

and then

srv02# ls /usr/local/bin/k*
ls: No match.
srv02# ls /usr/bin/k*
/usr/bin/kadmin /usr/bin/kdump /usr/bin/keylogout /usr/bin/killall 
/usr/bin/klist /usr/bin/krb5-config /usr/bin/ktrace
/usr/bin/kdestroy /usr/bin/keylogin /usr/bin/kgdb /usr/bin/kinit 
/usr/bin/kpasswd /usr/bin/ksu /usr/bin/ktrdump
srv02# ls /usr/lib/libgss*
/usr/lib/libgssapi.a /usr/lib/libgssapi_krb5.a 
/usr/lib/libgssapi_krb5_p.a /usr/lib/libgssapi_ntlm.so.10 
/usr/lib/libgssapi_spnego.a /usr/lib/libgssapi_spnego_p.a
/usr/lib/libgssapi.so /usr/lib/libgssapi_krb5.so 
/usr/lib/libgssapi_ntlm.a /usr/lib/libgssapi_ntlm_p.a 
/usr/lib/libgssapi_spnego.so
/usr/lib/libgssapi.so.10 /usr/lib/libgssapi_krb5.so.10 
/usr/lib/libgssapi_ntlm.so /usr/lib/libgssapi_p.a 
/usr/lib/libgssapi_spnego.so.10
srv02# ls /usr/local/lib/libgss*
ls: No match.

so it would seem that the /usr/local heimdal is now gone, but some 
heimdal is still left in /usr ?

looking at a different partition with a vanilla FreeBSD install I find 
the same files in /usr/lib and /usr/bin.
maybe I did not have to install kerberos package at all ?

I will play a bit more with this, but any more input would still be 
appreciated...

/Henrik
