A cgi script on my local mirror, which has worked flawlessly in the past (and continues to work on a remote host), is suddenly failing to verify passwords. I've traced it to a problem with crypt
perl -e "print crypt('abcdef', 'uvwxyz')"
In every instance, I get the same result: the first two characters of the salt, followed by a string of periods. I've tried this with both 5.6.0 (as provided by Redhat for their Linux 7.0), as well as ActivePerl 5.6.1 on the same Linux box. Both give the same results. I've also updated glibc, thinking that libcrypt.so might have been broken, but to no avail.
I must be overlooking something simple, but it's got me flummoxed. Has anyone else experienced this behavior?
