from mysql to ldap

[Zakki A]

i have some question about ldap authentication :
- i would like to know the benefit of ldap authentication compared to mysql
authentication
- right now i'm using mysql, if i want to use ldap auth. should i move my
user from mysql to ldap ? how to do it ?
- is there any effect to sqwebmail and qmailadmin ?

thanks for your help, it's nice if you also tell me how 'the taste' of ldap
is.
