We are running NetWare 6.5 SP6 with Apache 2.0.59 and iFolder 2.1.8.
iFolder was working fine for a month or so, until I installed MySQL
(although, I'm not 100% sure that this is when iFolder stopped working).
I tried uninstalling MySQL in an attempt to resolve the problem, but users
still receive an "Authentication Failed" error message on the client side.

I'm not sure if this is related to the problem (I remember seeing these
messages before connectivity became broken), but when Apache first loads,
these messages appear:

>20:58:50 20:58:50 Root certificate file for master ldap not found.

Requesting a new one from server.
>20:58:50 20:58:50 NIF CertHandler: Retrieved certificate of size=1324.


Once Apache has been running for a minute or two, the following error
messages repeat on the Apache server console (ignore the timestamp and
dnsname.com, I manually typed the errors so I copied/pasted the time and I
removed our actual dns name):

I tried extensively searching the knowledgebase and other users' forum
posts, but I was unsuccessful at restoring connectivity. I performed some
LDAP tests from a few TIDs, and I believe it is up and running. TCPCON
shows the server listening on ports 389 and 636. Any suggestions would be
most appreciated.

Thanks for the help,

Joe
