Besides the ability 44 to create and alias an extended provider, it also allows the same 45 extended authentication provider to be reference by multiple 46 locations.</p> 47 48</div> 49<div id="quickview"><h3 class="directives">Directives</h3> 50<ul id="toc"> 51<li><img alt="" src="/images/down.gif" /> <a href="#authnprovideralias"><AuthnProviderAlias></a></li> 52</ul> 53<h3>Topics</h3> 54<ul id="topics"> 55<li><img alt="" src="/images/down.gif" /> <a href="#example">Examples</a></li> 56</ul><ul class="seealso"><li><a href="#comments_section">Comments</a></li></ul></div> 57<div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 58<div class="section"> 59<h2><a name="example" id="example">Examples</a></h2> 60 61 <p>This example checks for passwords in two different text 62 files.</p> 63 64 <div class="example"><h3>Checking multiple text password files</h3><p><code> 65 66 # Check here first<br /> 67 <AuthnProviderAlias file file1><br /> 68 <span class="indent"> 69 AuthUserFile /www/conf/passwords1<br /> 70 </span> 71 </AuthnProviderAlias><br /> 72 <br /> 73 # Then check here<br /> 74 <AuthnProviderAlias file file2> <br /> 75 <span class="indent"> 76 AuthUserFile /www/conf/passwords2<br /> 77 </span> 78 </AuthnProviderAlias><br /> 79 <br /> 80 <Directory /var/web/pages/secure><br /> 81 <span class="indent"> 82 AuthBasicProvider file1 file2<br /> 83 <br /> 84 AuthType Basic<br /> 85 AuthName "Protected Area"<br /> 86 Require valid-user<br /> 87 </span> 88 </Directory><br /> 89 </code></p></div> 90 91 <p>The example below creates two different ldap authentication 92 provider aliases based on the ldap provider.
