mit-krb5 default plugins broken?

[coyhile]

Trying to bootstrap an MIT KDC based on mit-krb5-1.14.6, one sees the following behavior:

[root@krbtest ~]# kdb5_util create
Loading random data
Initializing database '/var/krb5kdc/principal' for realm 'LOCAL',
master key name 'K/M@LOCAL'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
kdb5_util: Unable to load requested database module 'db2': plugin symbol 'kdb_function_table' not found while creating database '/var/krb5kdc/principal'
[root@krbtest ~]#

Looking further, we see from truss (in relevant part):

93041:  ioctl(3, TCSETS, 0xFFFFBF7FFFDFF900)            = 0
93041:  sigaction(SIGINT, 0xFFFFBF7FFFDFF7E0, 0x00000000) = 0

/var/krb5kdc/principal93041:    write(2, " / v a r / k r b 5 k d c".., 22)      = 22

And looking at the directory called out there, we see

[root@krbtest ~]# ls /opt/local/lib/krb5/plugins/kdb/
libdb2.la  libdb2.so
[root@krbtest ~]#

Creating a symlink allows the operation to complete successfully:

[root@krbtest ~]# ln -s /opt/local/lib/krb5/plugins/kdb/libdb2.so /opt/local/lib/krb5/plugins/kdb/db2.so
[root@krbtest ~]#  kdb5_util create

The container where I was testing is base-64-lts@17.4.0. I'll see if I can repro with the previous LTS image. ETA: same behavior with base-64-lts@16.4.1

[coyhile]

I built this outside the pkgsrc framework by hand, and I do not see the behavior there. In fact, the output of the default generated Makefile from configure yields lib/krb5/plugins/kdb/db2.so.

Is it this that causes the problems here?

[mamash]

Not just that single patch, but the entire patch set that injects support for pkgsrc libtool, likely. That's something that's usually desirable, because a central sanctioned libtool helps avoid all kinds of peculiar problems that different upstreams may suffer from. I'll investigate.

I also hit this bug while trying to setup a quick test kdc

Loading random data
Initializing database '/var/krb5kdc/principal' for realm 'ACHERON.BE',
master key name 'K/M@ACHERON.BE'
You will be prompted for the database Master Password.

The service to start the kdc and kadmind are also missing from the mit-krb5 package.
