Trying to add LDAP extension. Using Uniform Server v8.6.7 on w2008 server with apache 2, php 5.4.8 LDAP DLL is uncommented in php.ini extension directory is correct but has forward slashes (the dll is in the directory already - from the original Uniform install - so assume it is correct version) php info does not show ldap working apache error log shows cannot load dll - only clue is possibly the forward slashes though may have missed something else changed forward slashes to back slashes and restart apache now error log shows cannot load dll from directory with double backslashes Error (same as forward slashes): PHP Startup: Unable to load dynamic library 'W:\\UniServer\\usr\\local\\php\\extensions\\php_ldap.dll' - The specified module could not be found.\r\n in Unknown on line 0 searched various posts here and on other forums and also tried to understand php docs to no avail. tried disabling another extension and that did not change either. Can only think we are missing a simple switch somewhere to enable extensions etc does Uniform server come with some kind of armoring (like ubuntu) to prevent system changes? TIA
