Where does QGIS load sqlplus and tnsping?
In that case, sqlplus and tnsping would get loaded from the C:\\OraClient11g\\ client, while QGIS would load the other client that is missing the sqlnet.ora file. You can set the the variables ORACLE_HOME and TNS_ADMIN to tell the Oracle client to load the admin directory that it specifies, rather than the default relative path.
Why is my LDAP connection failing in QGIS?
The LDAP connection may fail from QGIS because you have something like the Oracle Instant Client somewhere in the path before your C:OraClient11g client. In that case, sqlplus and tnsping would get loaded from the C:OraClient11g client, while QGIS would load the other client that is missing the sqlnet.ora file.
Is the instant client included in the bin folder in QGIS?
The version of QGIS that I have does have the instant client included in the bin folder, so you wither need to set TNS_ADMIN to use tns name conenctions, or create the Network/admin/ folders in the QGIS bin folders and copy your tnsnames.ora and sqlnet.ora file into it.
