You try to login with correct login and password. The result are one or two frames with the login screen again.
If your credentials are really correct then there is in the most cases a problem with the Perl module CGI::Session. Old versions of this module have problems with the flushing of data- especially the automatic flushing of data. OpenCA tries to handle this bug but the best solution is to remove the original module from your computer and to install a new one. You can install a new version from CPAN or you install OpenCA again. If OpenCA cannot find this module then it installs an actual version by itself.
This error message happens if you are using an apache without
mod_ssl but you specified mod_ssl
in
your access control configuration.
This happens if the configuration requires
ssl
but you are using http to access the interface.
The access to the interface is only allowed for some computers with special IP addresses and you have not a computer with one of these special addresses.
There is a problem with the algorithms which mod_ssl and your browser are using. The configuration tries to enforce some special algorithms for security reasons. Please contact your administrators for more informations.
The keylength of your certificate is too short if you are using a certificate. If you don't use a certificate then the Apache itself or your browser only support some too short asymmetric keys. Please contact your local administrators to find out more details.

If your browser startis a connection to webserver via https then the two software components try to negotiate about the cryptoalgorithms which they support. Usually they choose the strongest algorithm and longest keylength. Some export restricted browsers only support too short keylength. This is not allowed in security sensitive areas. Please ask your administrators for the exact specifications of your installation.
