Problem with AuthDBI

Hi all--I am getting the following error from AuthDBI:

DBD::Ingres::st execute failed: E_US0899 line 1, Cursor
's0_passwordfromecogpass' already open.

Here are my configuration options from httpd.conf:

# Apache::AuthDBI Authentication and Authorization set up. - wse - 10/07

PerlAuthenHandler Apache::AuthDBI::authen
PerlAuthzHandler Apache::AuthDBI::authz

PerlSetVar Auth_DBI_encrypted on

# DBI->connect($data_source, $username, $password)
PerlSetVar Auth_DBI_data_source dbi:Ingres:soltrane::janitor

# authentication: SELECT pwd_field FROM pwd_table WHERE uid_field=$user
PerlSetVar Auth_DBI_pwd_table ecog_passwords
PerlSetVar Auth_DBI_uid_field username
PerlSetVar Auth_DBI_pwd_field password

# authorization: SELECT grp_field FROM grp_table WHERE uid_field=$user
PerlSetVar Auth_DBI_grp_table ecog_groups
PerlSetVar Auth_DBI_grp_field accessgroup

Here is some version info:

Solaris 5.8
Ingres 2.0
Perl 5.8.8
Apache 2.2.4
mod_perl 2.0.3
DBI 1.06
AuthDBI 1.06

I am *not* loading DBI in my startup.pl. The Ingres test database
server has very few threads available.

I will gladly supply any other relevant information. Thanks.
