Please help me!! I have been struggling and trying trying to get rid of CommunicationExecption every time.. not sure.. If I am doing some stupid.. I am using spring-ldap-1.3.1.RELEASE.. We've decided to use spring ldap.. after our initial POC went well........ !!

First time I am calling my service.. its working very good with below configuration and pooled the DirContext which is created by DirContextPoolableObjectFactory
If I trigger same call for ldap search in few seconds... Its not creating new one.. using old one.. that also excellent.. here are the questions..

Q1) If I trigger same ldap search after a minute... testOnBorrow=false its welcoming with below error... with testOnBorrow=true, its giving error.. and working well.... why in a minute giving error.. how long will it be active.... with out error.. how to configure that for active object/connection for longer time... if we can ?

Q2) testOnBorrow doing some attempt to LDAP when the object/connection to ldap is not valid.....well, our LDAP admin says that its doing very bad search attempt...
Can we customise this search attempt using custom search criteria... instead of leaving it to DefaultDirContextValidator
