Possible errors when saving Active Directory
When Xeams accesses the LDAP (in this case Microsoft Active Directory), 
either to start the server or during configuration tasks, "LDAP: error code 49" 
can be encountered.
A typical error message could say:
Naming Exception. [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903C8, comment: AcceptSecurityContext error, 
data 52e, v23f0]
The number value appearing after 
data indicates the underlaying problem. The following table lists possible values for Microsoft Active Directory. 
	
		| 525 | user not found | 
	
		| 52e | invalid credentials | 
	
		| 530 | not permitted to logon at this time | 
	
		| 531 | not permitted to logon at this workstation | 
	
		| 532 | password expired | 
	
		| 533 | account disabled | 
	
		| 534 | The user has not been granted the requested logon type at this machine | 
	
		| 701 | account expired |
