Description of problem: SELinux does not allow changing NIS passwords even on the master. Version-Release number of selected component (if applicable): selinux-policy-3.12.1-106.fc20.noarch selinux-policy-targeted-3.12.1-106.fc20.noarch How reproducible: Attempt to change users password on NIS master Steps to Reproduce: 1. Log in as root 2. passwd <USER> 3. enter new password twice Actual results: [root@tycho ~]# passwd mythtv Changing password for user mythtv. New password: Retype new password: NIS password could not be changed. passwd: all authentication tokens updated successfully. Expected results: No error from yppasswdd Additional info: [root@tycho ~]# sealert -l 07abd312-da59-45de-a8e7-4c5a60d3ef3f SELinux is preventing /usr/sbin/rpc.yppasswdd from write access on the file /etc/.pwd.lock. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that rpc.yppasswdd should be allowed write access on the .pwd.lock file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
