LDAP Descriptor List does not open when Active Directory is used

Hello colleagues,

We have encountered a problem after migration the database naming from OID to AD. Namely, the list of LDAP descriptors remains empty (or it doesn't open when you click on the button) when AD is configured in ldap.ora. When I configure OID, everything works as desired.

The test with tnsping is fine, so basically the configuration fits.

I've tried to remove DEFAULT_ADMIN_CONTEXT parameter from ldap.ora, tnsping is still working, the LDAP Descriptor list in Toad doesn't open.

We are using Toad version with DB Admin Module.

Thank you very much & kind regards,
