Hi,I have deployed cas server 3.0.5 on tomcat 5.5.23. CAS talks to MySQL 5.0 
for authentication purpose. For this I made following modification to 
deployerConfigContext.xml.&lt;bean id="dataSource" 
class="org.apache.commons.dbcp.BasicDataSource"&gt;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&lt;property 
name="driverClassName"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; 
&lt;value&gt;com.mysql.jdbc.Driver&lt;/value&gt;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&lt;property name="url"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; 
&lt;value&gt;jdbc:mysql://localhost:3306/db&lt;/value&gt;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&lt;property name="username"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp; &lt;value&gt;user1&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;propert!
 y name="password"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; 
&lt;value&gt;user1&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&lt;/bean&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &lt;bean 
id="SearchModeSearchDatabaseAuthenticationHandler"&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
class="org.jasig.cas.adaptors.jdbc.SearchModeSearchDatabaseAuthenticationHandler"&nbsp;&nbsp;&nbsp;
 &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; abstract="false" singleton="true" 
lazy-init="default" autowire="default" 
dependency-check="default"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property&nbsp; 
name="tableUsers"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; &lt;value&gt;users&lt;/value&gt;&!
 nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&n
bsp; &nbsp; &lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &lt;property 
name="fieldUser"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; 
&lt;value&gt;userid&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; 
&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp; &lt;property 
name="fieldPassword"&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp; 
&lt;value&gt;password&lt;/value&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp; 
&lt;/property&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &nbsp; &lt;property name="dataSource" ref="dataSource" 
/&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; &lt;/bean&gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nb!
 sp; &nbsp;&nbsp;&nbsp; &nbsp;The applications deployed on tomcat are then 
integrated with CAS by modifying their respective web.xml (s) and server.xml of 
tomcat. When I try to login to my application the login is successful and 
everything works fine. If I leave tomcat and mysql running overnight and if I 
again try to login to my application next day I get CAS in Unavailable error. 
If I restart tomcat everything works fine again. What could be the possible 
reason for this? What is the solution to this problem?
