MORE INFORMATION

To help you to troubleshoot issue, it may be useful to turn on debug logging of the LDAP client. To turn on debug logging of the LDAP client:

1. Obtain and install the checked (debug) build of the Wldap32.dll file.
2. Start the program that you want to troubleshoot. Note that it must load or use the Wldap32.dll file.
3. Attach a debugger to the process that you started in step 2.
4. Edit the global "LdapDebug" variable by Oring one or more of the following values, and then "go" the program:

   #define DEBUG_TRACE1              0x00000001
   #define DEBUG_TRACE2              0x00000002

   #define DEBUG_FILTER              0x00040000
   #define DEBUG_BIND                0x00080000
   
   #define DEBUG_NETWORK_ERRORS      0x00100000

   #define DEBUG_PARSE               0x00400000
   #define DEBUG_REFERRALS           0x00800000
   
   #define DEBUG_SEARCH              0x01000000
   #define DEBUG_REQUEST             0x02000000
   #define DEBUG_CONNECTION          0x04000000
   #define DEBUG_INIT_TERM           0x08000000
   
   #define DEBUG_API_ERRORS          0x10000000
   #define DEBUG_STOP_ON_ERRORS      0x20000000 /* If set, stop on internal errors */

   #define DEBUG_ERRORS              0x80000000
   							

   Note that if you turn on DEBUG_HEAP, a large performance reduction occurs.
