You also report that the output of id is:

uid=45056(beq00871) gid=10513(Domain Users) groepen=547(Power Users),545(Users)

Note that your gid 10513 is not one of your groups (547, 545). 
This violates a basic Cygwin assumption, see
http://cygwin.com/ml/cygwin/2002-12/msg00264.html
http://cygwin.com/ml/cygwin/2002-12/msg00214.html
and this can lead to various problems. It causes an internal error
when you start Cygwin:
internal_getlogin: SetTokenInformation(TokenPrimaryGroup): Win32 error 1308 

So what's happening is that the non-privileged daemon gets a request 
for a login with   permanently_set_uid: uid=45090/gid=10513
This request can't be satisfied because 10513 is not a current group of
the daemon and it doesn't have the privilege to add groups.

The solution is simple: either edit /etc/passwd and change the gid to
547 or 545, or in Windows add the user to the Domain Users group.
