Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: ยป http://pecl.php.net/package/kadm5.
Note:
If this option is used without specifying the path to KADM5, PHP will use the built-in KADM5 client libraries. Users who run other applications that use KADM5 (for example, running PHP 4 and PHP 5 as concurrent apache modules, or auth-kadm5) should always specify the path to KADM5: --with-kadm5=/path/to/kadm5. This will force PHP to use the client libraries installed by KADM5, avoiding any conflicts.
A DLL for this PECL extension is currently unavailable. See also the building on Windows section.
