Hi All,

I want the system user authentication to get on my webpages.

I am using apache 2.4.33 with mod_authnz_external

I have following conifg added in httpd.conf

Code:


LoadModule authnz_external_module modules/mod_authnz_external.so

DefineExternalAuth archive_auth checkpassword "/bin/checkpassword /bin/true"


DocumentRoot "/home/tuser/apache2/htdocs"
<Directory "/home/tuser/apache2/htdocs">
    AllowOverride All
    Options Indexes FollowSymLinks
    AuthType Basic
    AuthName "Authentication Required"
    AuthBasicProvider external
    AuthExternal archive_auth
    Require all valid-user
</Directory>


When ever i start the httpd it gives me error as below

AH00526: Syntax error on line 169 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'AuthType', perhaps misspelled or defined by a module not included in the server configuration



Not sure..what went wrong , any of your suggestions would highly appreciated.

AuthType needs module mod_authn_core, see https://httpd.apache.org/docs/2.4/mod/mod_authn_core.html#authtype

xing thanks for the reply,

"AuthType Basic" is resolved still i get error with
"AuthBasicProvider".


Below are the modules it show , when i comment AuthBasicProvider

/home/test/apache2/bin/httpd -M
Loaded Modules:
core_module (static)
so_module (static)
http_module (static)
mpm_event_module (static)
authn_core_module (shared)
unixd_module (shared)
authz_core_module (shared)
authnz_external_module (shared)

Configration is as below

Code:



LoadModule authn_core_module modules/mod_authn_core.so
LoadModule unixd_module modules/mod_unixd.so
LoadModule authz_core_module modules/mod_authz_core.so
LoadModule authnz_external_module modules/mod_authnz_external.so

DefineExternalAuth archive_auth checkpassword "/bin/checkpassword /bin/true"

<Location />
    AuthType Basic
    AuthName "Authentication Required"
    AuthBasicProvider external
    AuthExternal archive_auth
    Require valid-user
</Location>





# /home/test/apache2/bin/httpd
AH00526: Syntax error on line 179 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'AuthBasicProvider', perhaps misspelled or defined by a module not included in the server configuration



I am following the below configuration provided for the module.





https://github.com/haegar/mod-auth-external/wiki/ConfigApache24#31-external-password-authenticators

3.1. External Password Authenticators
For normal user authentication, the following directives should be in the .htaccess file or <Directory> block:

AuthType Basic
AuthName <authname>
AuthBasicProvider external
AuthExternal <keyword>
Require valid-user
Here <authname> identifies what we are authenticating for - it usually appears in the browser's pop-up login window. <keyword> matches a keyword you defined with DefineExternalAuth or AddExternalAuth in step 2.


Any pointers would be really helpful for me here.

thanks
