We are having LDAP application problem with 2811 router running 12.3(8)T11 image.
Before this application worked with 2621 router running 12.2(4)T3 and 12.1(5)T12
Note: There is no LDAP Query configuration in router, for LDAP just it pass through (it will do normal packet routing, configuration attached for reference).
Now we are hearing different suggestions from different people.
1 Some people are saying that "This LDAP application will work only with 12.1 and 12.2"
2 Some people saying that "It works only with 26xx series router".
3 Some people recommending to upgrade to latest IOS in 12.3 or 12.4 series.
I am requesting all technicins to put some comments on it.
