我正在寻找如何将 GSSAPI 支持添加到我的 OpenLDAP 中？
当前设置
MIT Kerberos V + OpenLDAP
Kerberos bind to openldap
Able to issue kerberos tickets to my users (with kinit exampluser)
Able to ldapsearch -x uid=exampluser
Openldap端
server% ldapsearch -x -H ldapi:/// -b "" -LLL -s base -Z supportedSASLMechanisms
ldap_start_tls: Protocol error (2)
additional info: unsupported extended operation
dn:
supportedSASLMechanisms: DIGEST-MD5
supportedSASLMechanisms: EXTERNAL
supportedSASLMechanisms: CRAM-MD5
supportedSASLMechanisms: NTLM
supportedSASLMechanisms: LOGIN
supportedSASLMechanisms: PLAIN
客户端
client% ldapsearch uid=exampleuser
SASL/GSSAPI authentication started
ldap_sasl_interactive_bind_s: Authentication method not supported (7)
additional info: SASL(-4): no mechanism available: Couldn't find mech GSSAPI
客户端 ldap.conf
#
# LDAP Defaults
#
# See ldap.conf(5) for details
# This file should be world readable but not world writable.
BASE dc=example,dc=com
URI ldap://ldap.example.com
SASL_MECH GSSAPI
显然，错误很清楚，可以解释我的 ldap 请求没有找到验证机制。
我经历了许多教程和解释，但仍然无法找到如何“添加”该机制的任何地方。
谢谢什么是 SASL/GSSAPI？对于所有令人敬畏的解释。

我已经为 ldap 生成了一个密钥表，我在/etc/ldap/ldap.keytab中复制了它，并根据https://help.ubuntu.com/community/SingleSignOn编辑了/etc/default/slapd要求取消注释并给出导出 KRB5_KTNAME=/etc/ldap/ldap.keytab的路径
那个 ldap keytab 是这样生成的
kadmin: addprinc -randkey ldap/[email protected]
kadmin: ktadd -k ~/ldap.keytab ldap/[email protected]
我还有一个在安装开始时创建的 /etc/krb5.keytab
kadmin.local: listprincs
[email protected]
K/[email protected]
krbtgt/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
[email protected] (also in the ldap, can issue a ticket and everything)
[email protected] (same for him)
ldap/[email protected]
ktutil 结果
# ktutil
ktutil: read_kt /etc/ldap.keytab
ktutil: list
slot KVNO Principal
---- ---- ---------------------------------------------------------------------
1 2 ldap/[email protected]
2 2 ldap/[email protected]
3 2 ldap/[email protected]
4 2 ldap/[email protected]
ktutil: read_kt /etc/krb5.keytab
ktutil: list
