>Description:
In ./include/krb5/osconf.h, it has the line:
#define DEFAULT_KADM5_KEYTAB "/usr/local/var/krb5kdc/kadm5.keytab"
but kadmind cannot find it. Doing a ktace on kadmind, it seems that
it only looks in the file /etc/krb5.keytab and does not look at
/usr/local/var/krb5kdc/kadm5.keytab at all.
If I add the line
admin_keytab = FILE:/usr/local/var/krb5kdc/kadm5.keytab
to the [realms] section of the /usr/local/var/krb5kdc/kdc.conf
file (which kadmind does open and read), then the results are
exactly the same. I don't know if this is a valid line in the
kdc.conf file or not, there is such a line in the
.../src/config-files/kdc.conf example of the distibution, but there
is no mention of it in the man page. Then again, I have seen a couple
other example kdc.conf files that had stuff which is not mentioned
in the man page, so I guess this might be a documentation bug also.
>How-To-Repeat:
N/A
>Fix:
While not a "fix" per se., I can get kadmind to work by setting
the following environment variable:
setenv KRB5_KTNAME /usr/local/var/krb5kdc/kadm5.keytab
I think there may be other related problems (that is, problems
caused by whatever is causing this one) because if I use kadmin
and do a "ktadd host/tiehack.gilasoft.com", I get the error:
kadmin: Cannot write to specified key table while adding key to keytab
but if I do a "ktadd -k /etc/krb5.keytab host/tiehack.gilasoft.com", it
works correctly. I do not know what it's trying to do, I can't tell
from a ktrace. It doesn't try to open a file to write the keytab
before it gives the error.
