当我要在Linux机器上配置IPA Cleint (FreeIPA)时,我得到了这个错误。
Kerberos authentication failed

我的ipa服务器已经运行了一年多了。最近,当我尝试通过https或终端添加新用户时,它失败了,并显示以下错误消息。 IPA-Fehler 4203: DatabaseError
Server is unwilling to perform: Managed Entry Plugin rejected add operation (see errors log). 在错误日志中,我看到: [timestamp] [:warn] [pid 2731] [client xxx] failed to set perms (3140) on file (/var/run/ipa/ccaches/
我正在尝试将ubuntu docker容器与FreeIPA集成,在安装FreeIPA-client -install时遇到以下错误

我正在试着理解一段代码,在下面的代码中&(ipA[iLower + 1]到底代表什么(快速排序的分区函数?
void Partition(int* ipA, int iSize) {
// Partitions of size 0 or 1 are already sorted
if (iSize <= 1) {
return;
}
// Select a pivot from the array randomly
int iPivot = ipA[rand() % iSize];
// Indices of
该设置由一个FreeIPA和一个客户机组成,它们都驻留在同一主机上的非特权LXD容器中。容器和主机都运行Ubuntu16.04。所有设置基本上都是FreeIPA默认值,分别由ipa-server-install或ipa-client-install生成。
不可能切换到在FreeIPA目录中创建的用户:
# su testuser setgid: Invalid argument
# sudo -s -u testuser sudo: unable to change to runas gid: Invalid argument sudo: unable to change to runas g
在将NFS服务添加到IPA服务器(登录到IPA服务器和kinit admin之后)时,我遇到了问题。当我执行以下行时:
[root@ipa ~]# ipa service-add nfs/server1.example.com
我搞错了
ipa: ERROR: Host does not have corresponding DNS A/AAAA record
我已经正确配置了3台服务器,并在IPA服务器CentOS7.2中安装了FreeIPA。
我的IPA服务器配置
IP4.ADDRESS 192.168.1.105/24
IP4.GATEWAY:192.168.1.1
ipv4.dns:8
我在数据库里有一张表 username, ip
A , ipA1

C , ipC1
A , ipA2
C , ipC2 我需要提取具有不同ip的同一用户的所有行 即结果: username, ip
A , ipA1
C , ipC1
