We have seen a similar issue with OpenLDAP that required to set the
minimum security strength factor (SSF) to 1 instead of the default 0.
This default triggers a bug in the Java virtual machine Kerberos
support.
IPA uses the 389 directory server, and it also has the possibility to
configure this, as described here:
http://directory.fedoraproject.org/wiki/Minimum_SSF_Setting
To check that you can run a query like this in your IPA installation:
# kinit admin
# ldapsearch \
-H ldap://your_ipa_server \
-Y GSSAPI \
-LLL \
-b 'cn=config' \
-s base \
nsslapd-minssf
The output will probably be like this:
dn: cn=config
nsslapd-minssf: 0
The important thing there is the value 0. You can try to change it to
1,
via LDAP or modifying directly the file
/etc/dirsrv/slapd-YOUR-REALM/dse.ldif. Do this with the directory
server
stopped, and remember how to revert it in case things fail.
Let us know if this helps.
By the way, for those interested in how to change this in OpenLDAP, it
requires something like this:
# cat > fixssf.ldif <<'.'
dn: cn=config
replace: olcSaslSecProps
olcSaslSecProps: noanonymous,noplain,minssf=1
-
.
# ldapmodify -H ldapi:/// -Y EXTERNAL -f fixssf.ldif

That did the trick. I edited the file as I had no hope of getting an ldapmodify command
going on my own. That's why I installed IPA in the first place. :)
