If the Admin user password is changed from default and lost you can reset it through SQL server.
1) Open SQL Management Studio and run the following query.
select * from eg.sysuser,
2) Look for the SYSUSER_ID of “admin” user, in following example it’s 1.
1 admin Administrator OpenData Administrator
3) Run the query.
select * from eg.prop_val where obj_id = <SYSUSER_ID> and uom_id = 12
You should see something like this:
71 1 68 12 BEAF189A671D8FEE6263F28E54ACE81E6B34040E
4) Run following sql:
UPDATE EG.PROP_VAL
SET PROP_VAL = 'BEAF189A671D8FEE6263F28E54ACE81E6B34040E'
WHERE UOM_ID = 12 AND OBJ_ID = <SYSUSER_ID>
Admin password should be reset to default.
