Dear all,
I have my RTIR successfully installed and running, but it won't
recognize the GnuPG public and private key for every users created. Here
is my configurations parameter from /opt/rt3/etc/RT_Siteconfig.pm :

Set( %GnuPG,
~    Enable => 1,
~    OutgoingMessagesFormat => 'RFC', # Inline
~    AllowEncryptDataInDB   => 0,
);

Set(%GnuPGOptions,
~    homedir => '/opt/rt3/var/data/gpg',
~    keyserver => 'hkp://pgp.mit.edu:11371',
~    'auto-key-locate' => 'keyserver',
~    'auto-key-retrieve' => 1,
);

Here is the directory permission for the gpg --homedir:
drwxr-xr-x  3 root  www    512 Mar  6 12:50 gpg

And the /opt/rt3/var/data/gpg contents are:
total 16
drwxr-xr-x  3 root  www   512 Mar  6 12:50 .
drwxr-xr-x  4 root  www   512 Mar  4 17:58 ..
drw-r--r--  2 root  www   512 Mar  5 16:22 private-keys-v1.d
- -rw-r--r--  1 root  www  1166 Mar  5 16:22 pubring.gpg
- -rw-r--r--  1 root  www  1166 Mar  5 16:22 pubring.gpg~
- -rw-r--r--  1 root  www   600 Mar  5 16:22 random_seed
- -rw-r--r--  1 root  www  1315 Mar  5 16:22 secring.gpg
- -rw-r--r--  1 root  www  1280 Mar  5 16:22 trustdb.gpg

I am running RTIR on FreeBSD 6.3 + Apache1.3 + mod_perl1.x + Postgresql8.1.

Is there anything that I overlooked or is there any specific place i can
dump all the keys i need?

Thanks.
