7.4.3-0.15 condor_* daemon in the condor package (including condor_shadow) are not linked to libcrypt.so anymore. However, condor_* processes that are part of condor-qmf and condor-vm-gahp still link to libcrypt. Specifically,

This is ok for 0.16, please open a new BZ for the others.
I've misread the bug, which is about condor_shadow. condor_shadow no longer links against libcrypt on condor 7.4.3-0.16 (RHEL 4.8/5.5, i386/x86_64), so this bug is verified. |
