passed into SQL statement is never got effective at all.

Correct max_project_tree_depth config help text

The sample config file was edited manually and the help text for
the max_project_tree_depth didn't match what gets generated.

User ids that begin with 0 cannot authenticate through ldap

Currently, in the ldap2py function, several fields are attempted
to be converted to python friendly types.

In doing so, an attempt to convert a field to int() is attempted,
but in some cases, a user id may begin with a 0. When the user
attempts to authenticate, they will be rejected since any additional
query will use the id without the 0 in front.
