### Authenication problems

I have been trying to get webwork to authenticate users using our LDAP server, a microsoft product I believe. I had our IT dept set up a special user to bind to and followed the instructions with the additions for such a special user and get the following error when logging in as myself:

AUTH LDAP: bind error 49: The wrong password was supplied or the SASL credentials could not be processedI am still able to login using the password that I have in webwork (not my ldap password), meaning it's skipping that. I assume that the error comes from the server not getting the correct username/password for the special user. I have tried a number of ways to try the SEARCHDN variable, with no luck. I wonder if anyone has any suggestions. Also, if anyone has been successful with this with a microsoft LDAP server, if there was anything unusual that you needed to do. Peter

Peter, I am assuming that you have the server installed with PHP not just mod_perl when I recommend this, but I would try the PHP code below to just verify that your machine is connecting to the server properly. I found it was easier to get debugging done on the PHP side due to the availability of resources locally.
