那些遇到过的问题

Jupyterhub 在登录时创建用户和主页

Rad*_*onx 4 jupyter-notebook jupyterhub

我已经设置了带有 LDAP 身份验证的 jupyterhub 服务器。服务器和身份验证工作正常。但我的问题是，我需要在服务器上创建我想要手动登录的用户，否则他没有家，我会收到此错误。

如果凭据正确，有没有办法创建用户和家庭。谢谢

编辑：现在我将 jupyterhub-ldap-authenticator 更新到版本 0.3.0。直接支持自动主目录创建器。

我当前在 jupyterhub_config.py 文件中的 LDAP 部分配置如下所示：

c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'
c.LDAPAuthenticator.server_hosts =  ['ldap://ldap.example.com:389']
c.LDAPAuthenticator.bind_user_dn = 'uid=binduser,cn=users,dc=ldap,dc=example,dc=com'
c.LDAPAuthenticator.bind_user_password = 'Password'
c.LDAPAuthenticator.user_search_base = 'cn=users,dc=ldap,dc=example,dc=com'
c.LDAPAuthenticator.user_search_filter = '(&(objectClass=posixAccount)(uid={username}))'
c.LDAPAuthenticator.username_pattern = '[a-zA-Z0-9_.][a-zA-Z0-9_.-]{0,252}[a-zA-Z0-9_.$-]?'
c.LDAPAuthenticator.create_user_home_dir = True
c.LDAPAuthenticator.create_user_home_dir_cmd = ['mkhomedir_helper']

谢谢你的帮助。

找到了解决我的问题的方法。

\n\n

首先，我安装了 jupyterhub LDAP 身份验证器。

\n\n
pip3 install jupyterhub-ldapauthenticator\n
Run Code Online (Sandbox Code Playgroud)\n\n

安装后，我编辑了配置文件。

\n\n
nano /etc/jupyterhub/jupyterhub_config.py\n
Run Code Online (Sandbox Code Playgroud)\n\n

配置如下所示：

\n\n
c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'\nc.LDAPAuthenticator.server_hosts =  ['ldap://ldap.example.com:389']\nc.LDAPAuthenticator.bind_user_dn = 'uid=ldapbind,cn=users,dc=ldap,dc=example,dc=com\xe2\x80\x98\nc.LDAPAuthenticator.bind_user_password = \xe2\x80\x98Password\xe2\x80\x99\nc.LDAPAuthenticator.user_search_base = 'cn=users,dc=ldap,dc=example,dc=com\xe2\x80\x98\nc.LDAPAuthenticator.user_search_filter = '(&(objectClass=posixAccount)(uid={username}))'\nc.LDAPAuthenticator.username_pattern = '[a-zA-Z0-9_.][a-zA-Z0-9_.-]{0,252}[a-zA-Z0-9_.$-]?'\nc.LDAPAuthenticator.create_user_home_dir = True\nc.LDAPAuthenticator.create_user_home_dir_cmd = ['mkhomedir_helper']\n
Run Code Online (Sandbox Code Playgroud)\n\n

在下一步中，我安装了以下 LDAP 软件包。

\n\n
sudo apt-get install libnss-ldap libpam-ldap nscd\n
Run Code Online (Sandbox Code Playgroud)\n\n

安装时您可以对配置进行所需的更改。\n安装后，我需要重新配置软件包，因为我需要更改密码加密。

\n\n
sudo dpkg-reconfigure ldap-auth-config\n
Run Code Online (Sandbox Code Playgroud)\n\n

接下来，我更改了配置文件 ldap.conf。

\n\n
nano /etc/ldap/ldap.conf\n
Run Code Online (Sandbox Code Playgroud)\n\n

从：

\n\n
#BASE\xc2\xa0\xc2\xa0\xc2\xa0 dc=unixmen,dc=local\n#URI\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 ldap://192.168.1.100\n
Run Code Online (Sandbox Code Playgroud)\n\n

到：

\n\n
BASE\xc2\xa0\xc2\xa0\xc2\xa0 dc=ldap,dc=example,dc=com\nURI\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 ldap://ldap.example.com\n
Run Code Online (Sandbox Code Playgroud)\n\n

我编辑的第二个配置文件是 nsswitch.conf。\nldap 需要添加四次。

\n\n
passwd:\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 compat ldap\ngroup:\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 compat ldap\nshadow:\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 compat ldap\nnetgroup:       ldap\n
Run Code Online (Sandbox Code Playgroud)\n\n

更改后，需要重新启动服务。

\n\n
systemctl restart nscd\n
Run Code Online (Sandbox Code Playgroud)\n\n

像这样，我可以解决我的问题，而且它仍然对我有用。

\n
