When configuring JIRA to connect to LDAP directory with Read/Write permission, user could encounter such error as the following when trying to change their password. This error will be thrown when the LDAP directory has a certain password restrictions and the user input the password which does not meet the password requirements.

Quoted from here, the error thrown is LDAP error code 53 where it indicates

Indicates that the LDAP server cannot process the request because of server-defined restrictions. This error is returned for the following reasons: The add entry request violates the server's structure rules...OR...The modify attribute request specifies attributes that users cannot modify...OR...Password restrictions prevent the action...OR...Connection restrictions prevent the action.

In the future, it would be best to better handles the exception with mentioning

• To contact the administrator since an error has occured
• Mentioning the error of LDAP Error Code 53
