Limitation of OR Filter

[jthatcher]

Hi,

We are using Spring LDAP to implement a common LDAP query component. I hav e tried to implement a search using the OR filter. This works fine when there are only 100 values in my OR filter but when there are around 300 the query fails with no explicit error.

I checked the documentation and there is no mention of any restrictions. The filter encodes correctly but throws an exception when used to query my ldap server.

Does anyone know what the restrictions are?

Thanks

Jo

This is the error message I get. The code works fine when there are less parameters
