Ticket 49226 - Memory leak in ldap-agent-bin
    
    Bug Description:  We had a leak "somewhere" in the ldap-agent-bin
    code. This wasn't able to be easily traced, due to the output of:
    
    Direct leak of 29 byte(s) in 1 object(s) allocated from:
        #0 0x7f7c696e7880 in malloc (/lib64/libasan.so.4+0xde880)
        #1 0x7f7c691afca4 in ber_memalloc_x (/lib64/liblber-2.4.so.2+0x7ca4)
        #2 0x60400000034f  (<unknown module>)
    
    Fix Description:  The issue was that we were not freeing the attr
    and val from ldap_parse_line while parsing our entries.
