Description Dalibor Pospíšil 2013-08-07 09:55:22 EDT
Description of problem:
visudo shows cycle warning for following sudoers:

# cat ./sudoers
Host_Alias      HALIAS1 = host1
Host_Alias      HALIAS2 = HALIAS1, host2
Host_Alias      HALIAS3 = HALIAS1, HALIAS2
root HALIAS3 = /bin/echo hello

Also using -s option it says 'parse error in (null)'.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. visudo -cf ./sudoers
2. visudo -csf ./sudoers

Actual results:
visudo: Warning: cycle in Host_Alias `HALIAS1'
./sudoers: parsed OK

visudo: Error: cycle in Host_Alias `HALIAS1'
parse error in (null)

Expected results:
./sudoers: parsed OK

Additional info:
sudo-1.7.2p1-28.el5 behaves correctly
