| Doc Text: |
Cause: when fixing a problem with the master map parser, to properly defect map format associated with map type in the master map, the type comparison for yp maps used an incorrect length.
Consequence: map type yp isn't correctly matched which causes the corresponding map to not be read.
Fix: correct the length used in the comparison.
Result: yp maps are now correctly read.

I'll investigate. Ian When checking the code to see if I could see anything obvious I think I've already found where the problem is. I haven't done any testing at all yet so it's just a guess.

Patch - fix fix master map type check
I think I should create a test package with this patch just
in case this is all the problem is, then continue with trying
to reproduce and test the change myself.
I'll do that.

Patch - fix fix master map type check (updated)
This patch appears to fix the problem described.
A test package that appears to resolve the problem described here has been built and is located at: http://people.redhat.com/~ikent/autofs-5.0.5-109.type.2.el6/ Could you check and see if it resolves the problem please. I just tried the test package and it does, indeed, fix the problem. Thanks! Reproduced in autofs-5.0.5-109.el6.x86_64, the result is like following: Running test for 'bz1153130' using 'autofs-5.0.5-109.el6.x86_64' <--snap--> ls: cannot access /test/raven: No such file or directory Verified in autofs-5.0.5-112.el6, covers i386, x86_64, ppc64, s390x, the result is like following: bz1153130-READY:bz1153130-READY:bz1153130-READY <--snip--> Test bz1153130: SUCCESS Also run regression/bugzillas/stress test cases for autofs, no regression, works fine. So I change the status of this bug to be VERIFIED. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
