Apache 2.4 AH01695 [LDAP：ldap初始化失败] [未知（私有扩展）错误]

Question

We are upgrading from Apache 2.2 on RHEL5 to Apache 2.4.12 on RHEL7. I have added the LDAP configuration similar to before and I am prompted as expected for userid and password, but Apache is failing to logon and displays the following error in the log:

error_log [Thu Jul 02 16:28:08.277247 2015] [authnz_ldap:info] [pid 18923:tid 140442658866944] [client <>:53830] AH01695: auth_ldap authenticate: user <> authentication failed; URI /mytest/ [LDAP: ldap initialization failed][Unknown (private extension) error]

Is this a configuration directive or missing library issue? I am able to query the active directory using the ldapsearch from the server.

I have included the LocationMatch, Modules Loaded, and Configure options below:

Configuration for Location is:

<LocationMatch "/mytest">
    LogLevel debug
    AuthName "My Test Site"
    AuthType Basic
    AuthBasicProvider ldap
    AuthLDAPURL "ldap://ActiveDirectoryURL"
    AuthLDAPBindDN "CN=ServiceAccount"
    AuthLDAPBindPassword "ServicePassword"
    Require valid-user
</LocationMatch>

Related Modules Loaded are:

LoadModule authn_file_module modules/mod_authn_file.so
LoadModule authn_dbm_module modules/mod_authn_dbm.so
LoadModule authn_anon_module modules/mod_authn_anon.so

Configure directives were:

必须添加rpm apr-util-ldap才能使LDAP查询在其他apr / apr-util库之外起作用。
