LDAP debugging?

Hi,

I just installed YouTrack and am now trying to get the LDAP integration to work. However login always fails with [LDAP: error code 34 - invalid DN]. I am not sure if I have put the connection URL correctly, however without seeing what requests are being sent to the LDAP server it's hard to debug the issue and find out what I need to change. I have successfully integrated TeamCity with the LDAP server so in principle the connection should work. Is there some logfile where I can see what is being sent to the LDAP server?

Thanks :-)

Jan
