Summary
Bamboo fails to start after replacing the Atlassian Crowd instance being used for the external user directory with a new Crowd instance. This happens when a modification is made to a particular database table followed by a Bamboo startup or restart.
Environment
The solution has been tested on Bamboo 8 and 9 but should work on all supported versions of Bamboo.
Diagnosis
Bamboo is failing to start after changing the Crowd instance. The below error message is seen on the <bamboo-home>/logs/atlassian-bamboo.log file.

CWD_DIRECTORY_ATTRIBUTE table in Bamboo contains the required attributes required to connect with Crowd. Any incorrect property here will fail the connection between Bamboo and Crowd.
In this particular example application.password's value in the CWD_DIRECTORY_ATTRIBUTE table was modified with an unencrypted value.
Solution
The application.password's value should be encrypted before modifying the CWD_DIRECTORY_ATTRIBUTE's table.
This should be done using Bamboo Specs encryption. Steps are listed below
From the top navigation bar, select Specs > Sensitive data encryption.
Paste the content you want to encrypt in the text box.
Click Encrypt.
Note: Ensure that a backup of the database is taken before proceeding with the steps below:
Update the CWD_DIRECTORY_ATTRIBUTE table with the encrypted value as shown below;
# UPDATE CWD_DIRECTORY_ATTRIBUTE SET ATTRIBUTE_VALUE = 'new_application_password' WHERE ATTRIBUTE_VALUE = 'BAMSCRT@0@0@+5pSXYxi51kRcokvYa4+AWrA7OG7CxQdYeEJSloICWU=';
View the CWD_DIRECTORY_ATTRIBUTE to see the modification of the application.password's value.

Now the application starts successfully.
