Description Stefan Metzmacher 2017-03-01 17:17:04 UTC 
The fixes for bug #11830 trigger an endless loop in winbindd's forest trust scan logic.

- winbindd is member of W4EDOM-L4.BASE
- W4EDOM-L4.base has a two-way forest trust to BLA.BASE
- BLA.BASE has a 2nd tree-root domain BLA2.BASE

After the "winbind cache time" expires the parent winbindd
process loops and enumerates the trusts of BLA.BASE and BLA2.BASE.
