SVN - http checkout issue

Question

Dear Experts,

I have corrected my httpd config file after that I could able succeed the LDAP authentication

Now I am trying to checkout the files using the following code

SvnClient client = new SvnClient();
SvnCheckOutArgs coArgs = new SvnCheckOutArgs();
bool isCheckedOut = client.CheckOut("http://100.21.45.12:8999/SVN/myrepo/SDT", workingCopy, coArgs);

I am getting the following error

OPTIONS of 'http://100.21.45.12:8999/SVN/myrepo/SDT': 200 OK (http://100.21.45.12:8999)

Please help me
