UP5 breaks CIFS

[zkab]

I mount a Windows Public Share with autofs and it been working OK ... before UP5.
After UP5 it doesn't work any more.

My auto.master is:
/nfs /etc/auto.nfs --ghost
/cifs /etc/auto.cifs --ghost

and auto.cifs looks like:
My_Public -fstype=cifs,iocharset=utf8,credentials=/root/.cifscredentials,uid=1000,gid=1000,file_mode=0770,dir_mode=0770 ://helianra/Public

I can access the share with Nautilus which means that Windows gives the Public Share correctly to the network.
