我使用fedora23安装samba，服务起不来。重装也不行。
报错如下：
# systemctl status smb.service -l

看起来好像是库的问题，怎么破。

楼主最后解决了么

楼主，我也遇到类似的问题，最后怎么解决的？

经过尝试不同的方法，我这边也是一直失败，最后是发现需要更新一个库，不知道是不是和楼主一样的问题，在此把我的解决方法贴出来，希望有用吧：dnf install krb5-lib，根据提示会提示系统已经安装，默认不会给你安装update里面的程序，这个地方我最后是dnf install krb5-lib --best --allowerasing根据提示更新了两个文件之后启动smb.service就正常了

重装或者升级krb5-devel
yum install krb5-devel
或者, 找到
rpm -ivh krb5-devel-1.15.1-8.el7.x86_64.rpm krb5-libs-1.15.1-8.el7.x86_64.rpm libkadm5-1.15.1-8.el7.x86_64.rpm
