README.KRB4

To build the *API only* on an SP with AIX 4.2.1 / PSSP 2.4 and install in 
/usr/local/krb4, use the following manual procedure or run the attached script
(but look at it first:  set paths appropriate to your environment and note
that it destroys an old copy of the API if it is in the way).

NOTES: 
- This has not been tested in a long while.  We have stopped using KRB4
for pdsh on our SP's because we would occasionally overwhelm our KDC.
Also there is a bug which causes pdsh to run very slowly when pdsh has to
refresh the tgt for a node. --jg
- gcc needs to be in your PATH.

1) Obtain cns-96q4.tar.gz distribution from MIT and untar in ./kerberos.
   See: http://web.mit.edu/network/kerberos-form.html (verified this 3/98).
   Hmm there may be Y2K problems in this release...

2) Make sure the destination exists
	mkdir /usr/local/krb4
	chmod 755 /usr/local/krb4

3) Configure
	mkdir krb4.aix4
	cd krb4.aix4
	../kerberos/configure --prefix=/usr/local/krb4

3a) [You may skip this option and do 5a instead if you wish]

    Hand edit src/Makefile and src/include/Makefile and change 
	CONFDIR=$(LIBDIR) 
    to 
	CONFDIR=/etc

    *** We choose to go with /etc at LLNL because the API is installed on an
    *** NFS mounted partition and we don't want things compiled with the API
    *** to break if the partition isn't mounted.

3b) Depend
	make depend

4) Build/install the pieces we want
	cd src/util/et
	make all install
	cd ../ss
	make all install
	cd ../../include
	make all
	cp ../lib/kadm/kadm_err.h .
	cp ../lib/krb/krb_err.h .
	make install
	cd ../lib/acl
	make all install
	cd ../des
	make all install
	cd ../krb
	make all install
	cd ../kdb
	make all install
	cd ../kstream
	make all install
	cd ../kadm
	cp ../krb/krb_err.h .
	make all install

5) Perform a little cleanup	
	# return to directory that contains ./kerberos and ./krb4.aix4
	cp ./kerberos/src/include/kparse.h /usr/local/krb4/include
	cd /usr/local/krb4
	rm -rf man bin 
	cd include
	rm -f c-386aix.h c-386bsd.h c-386linux.h c-386sco.h c-alpha.h \
	    c-apollo.h c-aux.h c-hp68k.h c-hpsnake.h c-ibm370.h c-next.h \
	    c-pc.h c-pyr.h c-rtpc.h c-sgi.h c-sol2.h c-sun3.h c-sun386i.h \
	    c-sunos4.h c-tahoe.h c-ultmips.h c-vax.h

5a) [Only if step 3a was skipped] 
    Link SP config files into the locations wanted by the API
	cd /usr/local/krb4/lib
	ln -s /etc/krb.conf .
	ln -s /etc/krb.realms .
