maximum username length in ArcSDE Geodatabase

[DeminHu]

Hi,

I have an enterprise SQL Server ArcSDE geodatabase, I  have many window group users.

From ArcCatolog,  I grant privileges to the goups users, all of them fine  are except 2 groups. I got error : Invalid Parameter value passed to function.

I could not figure out why, but  these two groups have the longest user name, including the domain name, total are 33 character.

Is there a maximum username length restriction in ArcSDE Geodatabase user?

Thanks.

I changed the groups names, made them  shorter, the problem solved.

ArcSDE generally uses lowest common denominator.  Oracle's limit is 30 characters, but
ArcSDE limits the SE_MAX_OWNER_LEN to 32 characters (31 plus terminator), so it's
still possible to generate groups which are not RDBMS-independent.
