VQADMIN + LDAP

Hi, this is my first message in the list.

I´ve installed QMAIL + VPOPMAIL + QMAILADMIN + COURIERIMAP + LDAP

Almost everything is working fine.

But when I try to list a specific domain or view a email account, the
following error happens:

"500 - Internal Server Error"

"Premature end of script headers: /var/www/cgi-bin/vqadmin/vqadmin.cgi " in
/var/log/httpd/error_log

I think that could be some configuration about LDAP, because vqadmin can
add, delete domains successfully, and in these tasks, vqadmin doesn´t
authenticate in LDAP.

But, in the others, the authentication happens.

Any idea????

Thanks

Chuck
