I recently installad zope 2.5.1 on a debian machine and everything went well. 
I proved tid and passwod to zope duriing the installation. process as it 
asked.  

After the installation ,I successfuly accessed the zope through browser, but 
When I clicked on the "Zope Management Interface" page, and  input  the same 
id and passowrd which I provided during the installation, but it did not 
accept my id and password. I am not sure what went wrong and where to go from 
here.  Can anyone help and point me to the right direction. 

Thanks in adance !
