Error when performing search: getExtendedProperties [LDAP: error code 50

Question

Hi there,
We are currently running OAS 10.1.2. We have an application which is running Oracle Forms. To get access to these forms, the authenication is a combination of the user logging on to their windows domain, (AD SSO) and having the correct username and groups within Oracle OID and DAS.
We have a major problem at the moment in Production where every so often a user will get rejected for having insufficient access rights, and the UserID in the logs being Null. Yet if they try again it works.
Does anyone know why this might be happening for?
Here is the Forms log :

Answer 1

I fixed it in my environment.
formweb.cfg has oid_formsid and formsid_group_dn. Verify if these values are correct.
Also ensure that formsid_group_dn has no blank spaces after ',' (commas)
formsid_group_dn=cn=Logical Application Group,orclApplicationCommonName=formsApp_xyzhost_1224C3F0A73B11DBBFC783346A955D8F,cn=forms,cn=Products,cn=OracleContext
